[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 6 As shown, an embodiment of the utility model provides a box assembly, which includes a box 10, a power box 20 and a buffer structure 30. The front surface of the box 10 is a display module mounting surface 11, the power box 20 is arranged on the rear side of the box 10 and connected to the box 10, and the buffer structure 30 is abutted between the rear side of the box 10 and the front side of the power box 20.

[0032] The box assembly provided in this embodiment is applied, and the box assembly includes a box 10, a power box 20 and a buffer structure 30. The power box 20 is arranged on the rear side of the box 10 and connected to the box 10, and the buffer structure 30 is arranged between the rear side of the box 10 and the front side of the power box 20. When the flatness of the power box 20 in the front-to-back direction is poor, the buffer structure 30 clamped between the rear side of the box 10 and the front side of the power box 20 is easier to deform than the box 10. The buffer structure 30 is used to share the impact of the power box 20 with poor flatness, reduce the impact on the box 10, and reduce the risk of bending or deformation of the box 10, thereby improving the flatness reliability of the display module mounting surface, improving the flatness between the display modules installed on the display module mounting surface, improving the flatness of the display surface of the LED display device, and improving the display effect of the LED display device.

[0033] like Figures 1 to 6 As shown, the rear side of the box body 10 and / or the front side of the power box 20 are provided with abutment protrusions 40 , and the buffer structure 30 is provided corresponding to the abutment protrusions 40 and abuts and cooperates with the abutment protrusions 40 . It should be noted that the buffer structure 30 and the abutment protrusion 40 are arranged correspondingly, which means that the buffer structure 30 is a structure intermittently arranged on the rear surface of the case 10 corresponding to the abutment protrusion 40, so that after the power box 20 is connected to the case 10, the power box 20 and the case 10 are abutted against each other through the abutment protrusion 40 and the buffer structure 30, thereby reducing the abutment range between the power box 20 and the case 10, thereby avoiding the flatness of the power box 20 outside the abutment range corresponding to the abutment protrusion 40 and the buffer structure 30 from affecting the flatness of the case 10, avoiding the overall flatness of the power box 20 from affecting the flatness of the case 10, reducing the influence of the flatness of the power box 20 on the flatness of the case 10, further improving the flatness of the display surface of the LED display device, and improving the display effect of the LED display device.

[0034] The rear side of the box body 10 and / or the front side of the power box 20 is provided with an abutment protrusion 40, which has the following four embodiments:

[0035] (1) The abutment protrusion 40 is provided only on the rear side of the box body 10;

[0036] (2) The abutment protrusion 40 is provided only on the front side of the power supply box 20;

[0037] (3) The rear side of the box body 10 and the front side of the power box 20 are both provided with abutment protrusions 40, and the abutment protrusions 40 provided on the rear side of the box body 10 and the abutment protrusions 40 on the front side of the power box 20 are staggered;

[0038] (4) Both the rear side of the case 10 and the front side of the power box 20 are provided with abutment protrusions 40. The abutment protrusions 40 provided on the rear side of the case 10 and the abutment protrusions 40 provided on the front side of the power box 20 are provided correspondingly, and the buffer structure 30 is sandwiched between the abutment protrusions 40 provided on the rear side of the case 10 and the abutment protrusions 40 provided on the front side of the power box 20.

[0040] like Figures 1 to 6 As shown, the height of the abutting protrusion 40 in the front-to-back direction of the box body 10 is between 0.3 mm and 0.5 mm. By using the abutting protrusion 40 in the above size range, the gap between the power box 20 and the box body 10 is reduced, and impurities such as dust are prevented from entering the box body assembly through the gap between the power box 20 and the box body 10, while avoiding the flatness of the power box 20 outside the abutting range corresponding to the abutting protrusion 40 and the buffer structure 30 affecting the flatness of the box body 10.

[0041] Among them, in the embodiment of "the rear side of the case 10 and the front side of the power box 20 are both provided with abutment protrusions 40, the abutment protrusions 40 arranged on the rear side of the case 10 and the abutment protrusions 40 on the front side of the power box 20 are arranged correspondingly, and the buffer structure 30 is sandwiched between the abutment protrusions 40 arranged on the rear side of the case 10 and the abutment protrusions 40 on the front side of the power box 20", the height of the abutment protrusions 40 in the front-to-back direction of the case 10 is between 0.3mm and 0.5mm, which means that the sum of the height of the abutment protrusions 40 arranged on the rear side of the case 10 in the front-to-back direction of the case 10 and the height of the abutment protrusions 40 on the front side of the power box 20 in the front-to-back direction of the case 10 is between 0.3mm and 0.5mm.

[0042] It should be noted that the height of the abutting protrusion 40 in the front-rear direction of the box body 10 can be 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, and any value between 0.3 mm and 0.5 mm.
