[0036] 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.

[0037] like Figures 1 to 9 As shown, applying the technical solution of this embodiment, the box body of the LED display device includes a box body, a rotating shaft 20 and a support member 30. The box body includes a top plate 11, a bottom plate 12 and two side plates 13 arranged between the top plate 11 and the bottom plate 12. The rotating shaft 20 is rotatably arranged on the box body. The rotating shaft 20 extends along the front and rear directions of the box body, and the rotating shaft 20 rotates with its axis as the rotation center. The distance between the axis of the rotating shaft 20 and the plane where the side plate 13 is located is greater than the distance between the axis of the rotating shaft 20 and the plane where the bottom plate 12 is located. The support member 30 is connected to the rotating shaft 20, and the rotating shaft 20 drives the support member 30 to swing to have a retracted position and a protruding position. When the support member 30 is in the retracted position, the support surface of the support member 30 is located on the inner side of the side plate 13. When the support member 30 is in the protruding position, the support surface of the support member 30 protrudes downward from the bottom plate 12.

[0038] In this way, due to the setting position of the axis of the rotating shaft 20, when the rotating shaft 20 drives the support member 30 to rotate, the support surface of the support member 30 can be located on the inner side of the side plate 13 or protrude downward from the bottom plate 12. When the support member 30 is needed to support the box body, the rotating shaft 20 is rotated to switch the support member 30 to the protruding position, so that the support surface of the support member 30 protruding downward from the bottom plate 12 can support the box body. When the LED display device needs to be transported, the rotating shaft 20 is rotated to switch the support member 30 to the retracted position, so that the support surface of the support member 30 is located on the inner side of the side plate 13, reducing the bump caused by the support member 30 protruding from the box body. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the legs protruding from the box body are easily damaged when the LED display device is transported.

[0039] like Figures 1 to 9As shown, the support member 30 includes a connecting rod 31 and a support plate 33 connected to the connecting rod 31 at an angle, and the connecting rod 31 is connected to the rotating shaft 20 at an angle. The connecting rod 31 and the support plate 33 have simple structures and are easy to process. The arrangement of the connecting rod 31 makes the structure of the support member 30 more compact. The arrangement of the support plate 33 makes the support member 30 more reliable in supporting the box body.

[0040] like Figures 1 to 9 As shown, the support plate 33 is movably arranged on the connecting rod 31 so that the support plate 33 has a supporting position and an intermediate position. When the support plate 33 is in the supporting position, the support plate 33 is located below the bottom plate 12 and protrudes forward from the front surface of the box body. In this way, the support plate 33 protruding forward from the front surface of the box body can better support the box body and the display unit 80 on the front side of the box body. Since the support plate 33 protrudes forward from the front surface of the box body, at least part of the support plate 33 can be located directly below the display unit 80, reducing the collision with the display unit 80. When the support plate 33 is in the intermediate position, the support plate 33 is located on the rear side of the front surface of the bottom plate 12. When the support member 30 is switched to the retracted position, the setting of the support plate 33 being located on the rear side of the front surface of the bottom plate 12 facilitates the storage of the support plate 33.

[0041] In other embodiments, the support plate 33 is slidably disposed on the connecting rod 31 to switch between the supporting position and the intermediate position.

[0042] like Figures 1 to 9 As shown, the support plate 33 is rotatably arranged on the connecting rod 31, and the support plate 33 rotates with the axis of the connecting rod 31 as the rotation center. In the front-to-back direction, the rotation center of the support plate 33 is at a preset distance from the center of the support plate 33. In this way, when the support plate 33 switches between the supporting position and the intermediate position, the longer end of the support plate 33 in the front-to-back direction can protrude forward from the rear side of the front surface of the box body or the front surface of the bottom plate 12.

[0043] like Figures 1 to 9 As shown, the support plate 33 includes a plate body 331 and a telescopic plate 332 telescopically arranged on the plate body 331, and the telescopic plate 332 has an extended position extending out of the plate body 331 and a storage position retracted into the plate body 331. In this way, the length of the support plate 33 is adjustable, so as to improve the adaptability of the support member 30.

[0044] In this embodiment, when the display unit 80 is thicker, the retractable plate 332 is switched to the extended position to increase the length of the support plate 33 and improve the support stability of the support member 30 .

[0045] like Figures 1 to 9As shown, the support plate 33 includes a plate body 331 and a telescopic plate 332 telescopically arranged on the plate body 331, and the telescopic plate 332 has an extended position extending out of the plate body 331 and a storage position retracted into the plate body 331. In this way, the length of the support plate 33 is adjustable to improve the adaptability of the support member 30. The telescopic plate 332 is located at the end of the plate body 331, and the distance between the center of the telescopic plate 332 and the support plate 33 in the front-to-back direction is less than the distance between the rotation center of the telescopic plate 332 and the support plate 33. In this way, when the support plate 33 is in the supporting position, the length of the front end of the support plate 33 can be increased to adapt to the display unit 80 of different thicknesses on the box body. When the box body is replaced with a thicker display unit 80, the support stability of the support member 30 can be improved by increasing the length of the front end of the support plate 33.

[0046] like Figures 1 to 9 As shown, a receiving groove for receiving the telescopic plate 332 is provided on the plate body 331, and the box body of the LED display device also includes a first positioning structure arranged between the receiving groove and the telescopic plate 332. The first positioning structure includes a first positioning bead 41, a first positioning hole 42 and a second positioning hole 43. The first positioning bead 41 can be floatingly arranged on the telescopic plate 332, and the first positioning hole 42 and the second positioning hole 43 are arranged on the receiving groove at intervals. When the first positioning bead 41 is positioned and matched with the first positioning hole 42, the telescopic plate 332 is in the storage position. When the first positioning bead 41 is positioned and matched with the second positioning hole 43, the telescopic plate 332 is in the extended position. The provision of the first positioning bead 41, the first positioning hole 42 and the second positioning hole 43 can play a role in positioning the telescopic plate 332, so that the telescopic plate 332 can be better maintained in the storage position or the extended position. The structure of the first positioning structure is simple and easy to process.

[0047] In other embodiments, the first positioning bead 41 may be floatingly disposed on the receiving groove, and the first positioning hole 42 and the second positioning hole 43 are spaced apart and disposed on the telescopic plate 332 .

[0048] like Figures 1 to 9As shown, the connecting rod 31 is provided with a first mounting protrusion 32 protruding along its circumference. The box body of the LED display device also includes a second positioning structure arranged between the support plate 33 and the first mounting protrusion 32. The second positioning structure includes a second positioning bead 51, a third positioning bead 52, a third positioning hole 53 and a fourth positioning hole 54. The second positioning bead 51 and the third positioning bead 52 can be floatingly arranged on the first mounting protrusion 32, and the third positioning hole 53 and the fourth positioning hole 54 are arranged on the support plate 33 at intervals along the front-back direction. When the second positioning bead 51 is positioned and matched with the third positioning hole 53, and the third positioning bead 52 is positioned and matched with the fourth positioning hole 54, the support plate 33 is in a supporting position or an intermediate position. The arrangement of the second positioning bead 51, the third positioning bead 52, the third positioning hole 53 and the fourth positioning hole 54 can play a role in positioning the support plate 33, so that the support plate 33 can be better maintained in the supporting position or the intermediate position. The structure of the second positioning structure is simple and easy to process.

[0049] In other embodiments, the second positioning bead 51 and the third positioning bead 52 and the first mounting protrusion 32 can be floatingly disposed on the support plate 33, and the third positioning hole 53 and the fourth positioning hole 54 are spaced apart in the front-to-back direction.

[0050] like Figures 1 to 9 As shown, the rotating shaft 20 is provided with a second mounting protrusion 21 protruding along its circumference. The box body of the LED display device also includes a third positioning structure arranged between the box body and the second mounting protrusion 21. The third positioning structure includes a fourth positioning bead 61, a fifth positioning hole 62 and a sixth positioning hole 63. The fourth positioning bead 61 can be floatingly arranged on the second mounting protrusion 21, and the fifth positioning hole 62 and the sixth positioning hole 63 are arranged on the box body at intervals. When the fourth positioning bead 61 is positioned and matched with the fifth positioning hole 62, the support member 30 is in the retracted position. When the fourth positioning bead 61 is positioned and matched with the sixth positioning hole 63, the support member 30 is in the protruding position. The arrangement of the fourth positioning bead 61, the fifth positioning hole 62 and the sixth positioning hole 63 can play a positioning role on the rotating shaft 20, so that the support member 30 can be better maintained in the retracted position or the protruding position. The structure of the third positioning structure is simple and easy to process.

[0051] In other embodiments, the fourth positioning bead 61 may be floatingly disposed on the box body, and the fifth positioning hole 62 and the sixth positioning hole 63 are spaced apart and disposed on the second mounting protrusion 21 .

[0052] like Figures 1 to 9As shown, the box body of the LED display device also includes a rotating rod 71 and a top support member 72. The rotating rod 71 is rotatably arranged on the box body. The rotating rod 71 extends along the front-back direction of the box body, and the rotating rod 71 rotates with its axis as the rotation center. The distance between the axis of the rotating rod 71 and the plane where the side plate 13 is located is greater than the distance between the axis of the rotating shaft 20 and the plane where the top plate 11 is located. The top support member 72 is connected to the rotating rod 71, and the rotating rod 71 drives the top support member 72 to swing to have a retracted position and a top support position. When the top support member 72 is in the retracted position, the top support surface of the top support member 72 is located on the inner side of the side plate 13. When the top support member 72 is in the top support position, the support surface of the top support member 72 protrudes upward from the top plate 11. In this way, the top support member 72 in the top support position can protrude upward from the top plate 11, so that the support surface of the top support member 72 can be located above the display unit 80, so as to prevent the external collision with the display unit 80, thereby protecting the display unit 80. The top support member 72 in the retracted position can facilitate the splicing operation of multiple LED display devices. In this embodiment, the top support member 72 has the same structure as the support member 30.

[0053] In this embodiment, when the telescopic plate 332 is in the storage position, the support plate 33 is in the middle position, and the support member 30 is in the retracted position, the support surface of the support member 30 is located on the inner side of the side plate 13. When the support member 30 is in the protruding position, the support plate 33 is in the supporting position, and the telescopic plate 332 is in the extended position, the support member 30 supports the box body and is located directly below the display module.

[0054] In this embodiment, when the box is transported alone, the support member 30 is switched to the retracted position, and the top support member 72 is switched to the retracted position. The box body is rectangular, and the rotating shaft 20 and the rotating rod 71 are both arranged at the corners of the rectangle. When the box with the display unit 80 installed is transported, the support member 30 is switched to the protruding position, and the top support member 72 is switched to the top support position to protect the corners of the display unit 80 and reduce the bumps and damage to the display unit 80 during transportation. By applying the technical solution of this embodiment, the positions of the support member 30 and the top support member 72 can be adjusted according to the actual conditions of the components during transportation, so as to better protect the components of the LED display device and reduce the losses caused by bumps during transportation.

[0055] The present application also provides an LED display device, which includes a display unit 80 and a box body disposed at the rear side of the display unit 80, and the box body is the box body of the above-mentioned LED display device. Since the box body of the above-mentioned LED display device can solve the problem in the related art that the legs protruding from the box body are easily damaged when the LED display device is transported, the LED display device having the box body can solve the same technical problem.
