Description

Technical Field

[0001] This invention relates to the field of LED display technology, and more specifically, to an LED cabinet and an LED display device having the same. Background Technology

[0002] With the continuous development of LED display technology, various LED display devices are increasingly being used in different scenarios. Typically, larger LED displays are composed of multiple LED cabinets spliced ​​together according to certain rules, such as multiple LED cabinets arranged in an N*M array (where N and M are both positive integers). In related technologies, multiple LED display modules with LED light panels are set on the front side of the LED cabinet.

[0003] LED light boards contain a large number of fragile LED beads. If the light board is subjected to external impact during handling, the LED beads may be damaged, affecting the display function of the LED display module. Typically, protective structures are installed on the LED cabinet to protect the LED display module. Generally, these protective structures have a protective state and a retractable state when stored inside the LED cabinet. However, even when in the protective state, the structure can still be subjected to external interference during handling, causing it to lose its protective function and increasing the likelihood of damage to the LED display module.

[0004] Therefore, there is a problem in this field that the protective structure cannot be maintained in a protective state continuously. Summary of the Invention

[0005] The main objective of this invention is to provide an LED enclosure and an LED display device having the same, so as to solve the problem that the protective structure in related technologies cannot be continuously maintained in a protective state.

[0006] To achieve the above objectives, according to one aspect of the present invention, an LED enclosure is provided, comprising: an enclosure base; an LED display module disposed on the front side of the enclosure base; and an anti-collision structure disposed on the side wall of the enclosure base. The anti-collision structure includes a fixing sleeve, an anti-collision part, and a locking member. The fixing sleeve is disposed on the enclosure base. The anti-collision part includes a rotating core rotatably disposed within the fixing sleeve and an extension connected to the rotating core. The extension has an anti-collision position protruding forward from the LED display module and a retractable position within the enclosure base. The locking member has a locked position and an unlocked position. When the locking member is in the locked position, the rotating core engages with the fixing sleeve to prevent rotation and keeps the extension in the anti-collision position. When the locking member is in the unlocked position, the rotating core is rotatable relative to the fixing sleeve and allows the extension to rotate from the anti-collision position to the retractable position.

[0007] Furthermore, the fixed sleeve is provided with a limiting part, and the locking member includes a locking rod and a locking protrusion provided on the locking rod. The locking rod is movably inserted into the rotating core along the extending direction of the rotating core. The locking rod is anti-rotatingly engaged with the rotating core. The locking rod moves to switch the locking member between the locked position and the unlocked position. When the locking member is in the locked position, the locking protrusion is anti-rotatingly engaged with the limiting part. When the locking member is in the unlocked position, the locking protrusion is separated from the limiting part.

[0008] Furthermore, when the locking element is in the locked position, the outer end of the locking lever protrudes beyond the outer end of the rotating core; when the locking element is in the unlocked position, the outer end of the locking lever retracts into the range of the outer end of the rotating core.

[0009] Furthermore, the anti-collision structure also includes a first reset member disposed between the anti-collision part and the locking member, the first reset member applying a first reset force to the locking member so that the locking member remains in the locked position.

[0010] Furthermore, the locking lever includes a lever body and a first anti-rotation protrusion disposed at the outer end of the lever body.

[0011] Furthermore, the locking lever includes a lever body, a locking protrusion is disposed on the inner end of the lever body, and a limiting part includes an anti-rotation groove disposed on the inner end face of the fixing sleeve. When the locking member is in the locked position, the locking protrusion engages with the anti-rotation groove to prevent rotation. When the locking member is in the unlocked position, the locking protrusion disengages inward from the anti-rotation groove.

[0012] Furthermore, the locking protrusion includes a locking plate and a lug extending radially from the rotating core. The lug is disposed on the radial outer surface of the locking plate. The locking plate is provided with an anti-rotation through hole. The inner end of the rod body is provided with a second anti-rotation protrusion. The second anti-rotation protrusion is inserted into the anti-rotation through hole and engages with the anti-rotation through hole to prevent rotation. The locking protrusion is connected to the rod body by a first fastener passing through the anti-rotation through hole and the second anti-rotation protrusion.

[0013] Furthermore, the fixing sleeve is a cylindrical structure with a second through hole, the rotating core is disposed in the second through hole, the extension includes an anti-collision plate disposed at the outer end of the rotating core, the anti-collision structure includes a sliding assembly, the sliding assembly includes an oblique sliding groove and a sliding block that slides with the oblique sliding groove, one of the oblique sliding groove and the sliding block is disposed on the radial outer surface of the rotating core, and the other of the oblique sliding groove and the sliding block is disposed on the radial inner wall of the second through hole.

[0014] Furthermore, the anti-collision structure also includes a second reset member disposed between the rotating core and the fixed sleeve, the second reset member applying a second reset force to the rotating core so that the protrusion remains in the anti-collision position.

[0015] Furthermore, a first retaining ring is provided on the radial outer surface of the rotating core, a second retaining ring is provided on the radial inner wall of the second through hole, and a second reset member is provided between the radial outer surface of the rotating core and the radial inner wall of the second through hole, with the two ends of the second reset member abutting against the first retaining ring and the second retaining ring respectively.

[0016] Furthermore, the anti-collision structure includes a first anti-collision structure and a second anti-collision structure. The housing base has an installation side wall, and the first anti-collision structure and the second anti-collision structure are respectively provided at both ends of the installation side wall. When the protrusion of the first anti-collision structure is in the anti-collision position, the anti-collision plate of the first anti-collision structure protrudes forward and outward from the installation side wall of the housing base; and / or, when the protrusion of the second anti-collision structure is in the anti-collision position, the anti-collision plate of the second anti-collision structure protrudes forward and outward from the installation side wall of the housing base.

[0017] Furthermore, the fixing sleeve has a cylindrical structure and a second through hole, the rotating core is disposed in the second through hole, the extension includes a collision protection plate disposed at the outer end of the rotating core, a first receiving groove is disposed on the side wall of the housing base, the fixing sleeve is disposed in the first receiving groove, the LED housing also includes a positioning component, the positioning component includes a positioning protrusion and a positioning groove that positions and cooperates with the positioning protrusion, one of the positioning protrusion and the positioning groove is disposed in the first receiving groove, and the other of the positioning protrusion and the positioning groove is disposed on the fixing sleeve.

[0018] Furthermore, a second receiving groove communicating with the first receiving groove is provided on the side wall of the cabinet base. The LED cabinet also includes a second fastener provided in the second receiving groove. A positioning protrusion is provided on the fixing sleeve, and a positioning groove is provided in the first receiving groove. The outer end face of the fixing sleeve or the outer surface of the positioning protrusion cooperates with the stop of the second fastener to restrict the fixing sleeve from disengaging from the first receiving groove.

[0019] Furthermore, the fixing sleeve includes a first arc-shaped plate and a second arc-shaped plate. The first arc-shaped plate has a first protruding edge on both sides, and the second arc-shaped plate has a second protruding edge on both sides. The outer surface of the positioning protrusion cooperates with the second fastener stop, and the corresponding first and second protruding edges fit together to form the positioning protrusion.

[0020] Furthermore, a third receiving groove is provided on the side wall of the box body base. The third receiving groove extends forward through the box body base. The first receiving groove and the second receiving groove are both located on the bottom wall of the third receiving groove. The outer end of the second fastener is lower than or flush with the bottom wall of the third receiving groove. When the protrusion is in the storage position, the anti-collision plate is completely stored in the third receiving groove.

[0021] According to another aspect of the present invention, an LED display device is provided, including an LED housing, wherein the LED housing is the LED housing described above.

[0022] According to the technical solution of this invention, the anti-collision structure includes a fixed sleeve, an anti-collision part, and a locking member. The fixed sleeve is disposed on the housing base. The anti-collision part includes a rotating core and an extended part connected to the rotating core. The rotating core is rotatably disposed relative to the fixed sleeve. The rotating core drives the extended part to move between an anti-collision position and a retracted position. When the extended part is in the anti-collision position, the extended part protrudes forward from the LED display module to protect the LED display module. When the extended part is in the retracted position, the extended part is within the housing base to ensure that the gap between multiple LED housings is not too large when spliced ​​together, thus affecting the display effect. The locking member has a locked position and an unlocked position. When the locking member is in the unlocked position, the rotating core is rotatable relative to the fixed sleeve, and the rotation of the rotating core drives the extended part to move between the protective position and the retracted position. When the locking member is in the locked position, the rotating core does not rotate relative to the fixed sleeve, and the extended part will not rotate after being subjected to external force, thereby keeping the extended part in the anti-collision position and enabling the extended part to continuously protect the LED display module. Therefore, the technical solution of this application can effectively solve the problem that the protective structure in related technologies cannot be continuously maintained in a protective state.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figures 1 to 7As shown, this application provides an LED cabinet. An embodiment of the LED cabinet of this application includes: a cabinet base 10; an LED display module disposed on the front side of the cabinet base 10; and an anti-collision structure 20 disposed on the side wall of the cabinet base 10. The anti-collision structure 20 includes a fixing sleeve 21, an anti-collision part 22, and a locking member 23. The fixing sleeve 21 is disposed on the cabinet base 10, and the anti-collision part 22 includes a rotating core 221 rotatably disposed within the fixing sleeve 21 and an extension connected to the rotating core 221. Part 222 has an extension portion 222 that protrudes forward from the LED display module to form an anti-collision position and a storage position within the range of the housing base 10. The locking member 23 has a locking position and an unlocking position. When the locking member 23 is in the locking position, the rotating core 221 engages with the fixed sleeve 21 to prevent rotation and keep the extension portion 222 in the anti-collision position. When the locking member 23 is in the unlocking position, the rotating core 221 is rotatable relative to the fixed sleeve 21 and can rotate the extension portion 222 from the anti-collision position to the storage position.

[0047] Using the technical solution of this embodiment, the anti-collision structure 20 includes a fixing sleeve 21, an anti-collision part 22, and a locking member 23. The fixing sleeve 21 is disposed on the housing base 10. The anti-collision part 22 includes a rotating core 221 and an extension 222 connected to the rotating core 221. The rotating core 221 is rotatably disposed relative to the fixing sleeve 21. The rotating core 221 drives the extension 222 to move between the anti-collision position and the storage position. When the extension 222 is in the anti-collision position, the extension 222 protrudes forward from the LED display module to protect the LED display module. When the extension 222 is in the storage position, the extension 222 is within the range of the housing base 10 to ensure that the splicing gap between multiple LED housings is not too large and affects the display effect when multiple LED housings are spliced ​​together. The locking member 23 has a locked position and an unlocked position. When the locking member 23 is in the unlocked position, the rotating core 221 can rotate relative to the fixed sleeve 21. The rotation of the rotating core 221 can drive the extension 222 to move between the protective position and the storage position. When the locking member 23 is in the locked position, the rotating core 221 will not rotate relative to the fixed sleeve 21, and the extension 222 will not rotate after being subjected to external force, thereby keeping the extension 222 in the anti-collision position, and thus enabling the extension 222 to continuously protect the LED display module. Therefore, the technical solution of this embodiment can effectively solve the problem that the protective structure in the related art cannot be continuously maintained in the protective state.

[0048] It should be noted that the "front" used in this article to describe direction refers to... Figure 8 The LED cabinet shown is facing the viewer; the word "back" used to describe the orientation refers to... Figure 8The LED cabinet shown is located away from the viewer. "Within the range of the cabinet base 10" means that the projection of the protrusion 222 on the horizontal plane is completely within the projection of the cabinet base 10 on the horizontal plane, and the projection of the protrusion 222 on the vertical plane is completely within the projection of the cabinet base 10 on the vertical plane.

[0049] like Figures 1 to 4 As shown, the fixed sleeve 21 is provided with a limiting part 211, and the locking member 23 includes a locking rod 231 and a locking protrusion 232 provided on the locking rod 231. The locking rod 231 is movably inserted through the rotating core 221 along the extending direction of the rotating core 221. The locking rod 231 and the rotating core 221 are anti-rotationally engaged. The locking rod 231 moves to switch the locking member 23 between the locked position and the unlocked position. When the locking member 23 is in the locked position, the locking protrusion 232 and the limiting part 211 are anti-rotationally engaged. When the locking member 23 is in the unlocked position, the locking protrusion 232 and the limiting part 211 are separated. When the locking protrusion 232 is engaged with the limiting part 211 to prevent rotation, the locking member 23 will not rotate relative to the fixed sleeve 21, and the locking rod 231 is engaged with the rotating core 221 to prevent rotation, so that the rotating core 221 will not rotate relative to the fixed sleeve 21, thereby keeping the extension 222 in the anti-collision position, thus realizing the function of the extension 222 continuously protecting the LED display module; when the locking protrusion 232 is disengaged from the limiting part 211 to prevent rotation, the locking member 23 can rotate relative to the fixed sleeve 21, so that the rotating core 221 can also rotate relative to the fixed sleeve 21, thereby allowing the rotating core 221 to drive the extension 222 to move between the anti-collision position and the storage position.

[0050] like Figure 1 as well as Figure 2 As shown, when the locking member 23 is in the locked position, the outer end of the locking lever 231 protrudes beyond the outer end of the rotating core 221. When the locking member 23 is in the unlocked position, the outer end of the locking lever 231 retracts to the range of the outer end of the rotating core 221. When it is necessary to move the locking member 23 from the locked position to the unlocked position, pressure is applied to the outer end of the locking lever 231 toward the inner end of the locking lever 231, causing the outer end of the locking lever 231 to retract to the range of the outer end of the rotating core 221. When the protrusion 222 is subjected to multi-directional forces, the locking member 23 will not move to the unlocked position, thus keeping the protrusion 222 in a state where it does not rotate relative to the housing base 10. Only when the outer end of the locking lever 231 retracts to the range of the outer end of the rotating core 221 will the locking member 23 move to the unlocked position, allowing the rotating core 221 to rotate relative to the fixed sleeve 21.

[0051] Furthermore, in this embodiment, the LED cabinets are used to assemble an LED display device. When the LED cabinets are transported individually, the protrusion 222 needs to be kept in the anti-collision position to protect the LED display module. When multiple LED cabinets are assembled, the protrusion 222 needs to be switched to the storage position to avoid affecting the display effect of the LED display device. By setting the driving method for switching the locking member 23 from the locked position to the unlocked position to pressing the locking lever 231, when assembling the LED cabinets, the side wall of the LED cabinet or the locking lever 231 on the LED cabinet will press the locking lever 231 on the adjacent LED cabinet, causing the locking member 23 to switch to the unlocked position. This allows the protrusion 222 on the adjacent LED cabinet to switch to the storage position without requiring additional operation from the operator.

[0052] It should be noted that the term "outer" used in this article to describe direction refers to... Figure 8 The side facing outwards from the LED enclosure shown in the diagram, where "inside" is used in this text to describe orientation, refers to... Figure 8 The side facing the inside of the LED housing is shown. "Within the range of the outer end of the rotating core 221" means that the projection of the outer end of the locking lever 231 on the horizontal plane falls completely within the projection of the outer end of the rotating core 221, and the projection of the outer end of the locking lever 231 on the vertical plane falls completely within the projection of the outer end of the rotating core 221 on the vertical plane.

[0053] like Figure 2 as well as Figure 4 As shown, the anti-collision structure 20 also includes a first reset member 24 disposed between the anti-collision part 22 and the locking member 23. The first reset member 24 applies a first reset force to the locking member 23 to keep the locking member 23 in the locked position. In this embodiment, the first reset member 24 applies a first reset force toward the outer end of the rotating core 221 to the locking lever 231, so that the locking member 23 remains in the locked position when no external force is applied, or after the external force is removed (specifically after the two adjacent LED boxes are separated), the locking member 23 can switch from the unlocked position to the locked position and remain in the locked position, thereby keeping the protrusion 222 in the anti-collision position. By setting the first reset member 24, the locking lever 231 can automatically reset to the unlocked position, and no additional operation is required from the operator.

[0054] like Figure 1 , Figure 2 , Figure 4 as well as Figure 6As shown, the locking lever 231 includes a lever body 2311 and a first anti-rotation protrusion 2312 disposed at the outer end of the lever body 2311. The rotating core 221 has a first through hole 2211, which includes a first mounting section 2212 and a second mounting section 2213. The maximum radial dimension of the first mounting section 2212 is greater than the maximum radial dimension of the second mounting section 2213. A stepped surface 2214 is provided between the first mounting section 2212 and the second mounting section 2213. The lever body 2311 passes through the second mounting section 2213. The first anti-rotation protrusion 2312 is located in the first mounting section 2212 and engages with the first mounting section 2212 to prevent rotation. A first reset member 24 is disposed in the first mounting section 2212. The two ends of the first reset member 24 abut against the first anti-rotation protrusion 2312 and the stepped surface 2214, respectively.

[0055] In this embodiment, the first reset member 24 is a compression spring. The maximum radial dimension of the first mounting section 2212 is greater than the maximum radial dimension of the second mounting section 2213, thereby forming a stepped surface 2214 between the first mounting section 2212 and the second mounting section 2213. The first mounting section 2212 includes a first hole section 2215 and a second hole section 2216 that are interconnected. The maximum radial dimension of the first hole section 2215 is greater than the maximum radial dimension of the second hole section 2216, thereby forming a limiting surface 2217 between the first hole section 2215 and the second hole section 2216. The first reset member 24 is disposed within the first mounting section 2212. One end of the compression spring abuts against the stepped surface 2214, and the other end of the compression spring... One end abuts against the first anti-rotation protrusion 2312; when the first anti-rotation protrusion 2312 is subjected to a force toward the inner end of the locking rod 231, the first anti-rotation protrusion 2312 retracts to the first hole section 2215 until the first anti-rotation protrusion 2312 abuts against the limiting surface 2217, at which time the locking member 23 is in the unlocked position; when the force applied to the first anti-rotation protrusion 2312 toward the inner end of the locking rod 231 disappears, the first reset member 24 applies a first reset force to the first anti-rotation protrusion 2312 away from the inner end of the locking rod 231, causing the first anti-rotation protrusion 2312 to move toward the inner end away from the locking rod 231, thereby causing the locking member 23 to return to the locked position.

[0056] It should be noted that, in this embodiment, the circular hole structure of the second mounting segment 2213, the "radial dimension of the second mounting segment 2213" mentioned above, "the maximum radial dimension of the first mounting segment 2212 is greater than the maximum radial dimension of the second mounting segment 2213" refers to the hole diameter of the second mounting segment 2213, and the "radial dimension of the first mounting segment 2212" refers to the length of the straight line segment obtained by the corresponding hole wall of the first mounting segment 2212 through the axis of the first mounting segment 2212.

[0057] like Figures 1 to 4 as well as Figure 7As shown, the locking lever 231 includes a lever body 2311, a locking protrusion 232 disposed on the inner end of the lever body 2311, and a limiting part 211 including an anti-rotation groove 2111 disposed on the inner end face of the fixing sleeve 21. When the locking member 23 is in the locked position, the locking protrusion 232 engages with the anti-rotation groove 2111 to prevent rotation. When the locking member 23 is in the unlocked position, the locking protrusion 232 disengages inward from the anti-rotation groove 2111. When a force is applied to the locking lever 231 toward the inner end of the locking lever 231, the lever body 2311 moves toward the interior of the housing base 10, thereby causing the locking protrusion 232 to also move toward the interior of the housing base 10, so that the locking protrusion 232 disengages from the anti-rotation groove 2111, thereby allowing the rotating core 221 to rotate relative to the fixing sleeve 21.

[0058] like Figures 1 to 4 as well as Figure 7 As shown, the locking protrusion 232 includes a locking plate 2321 and a lug 2322 extending radially from the rotating core 221. The lug 2322 is disposed on the radial outer surface of the locking plate 2321. The locking plate 2321 is provided with an anti-rotation through hole 2323. The inner end of the rod body 2311 is provided with a second anti-rotation protrusion 2313. The second anti-rotation protrusion 2313 is inserted into the anti-rotation through hole 2323 and anti-rotationally engages with the anti-rotation through hole 2323. The locking protrusion 232 is connected to the rod body 2311 by a first fastener 25 passing through the anti-rotation through hole 2323 and the second anti-rotation protrusion 2313. The anti-rotation engagement of the lug 2322 with the anti-rotation groove 2111 prevents the locking rod 231 from rotating with the fixing sleeve 21. The anti-rotation engagement of the second anti-rotation protrusion 2313 with the anti-rotation through hole 2323 prevents the locking rod 231 from rotating with the locking plate 2321. In this embodiment, the assembly steps of the rotating core 221 of the locking member 23 are as follows: after passing the rod body 2311 through the first through hole 2211, the locking protrusion 232 is connected to the inner end of the rod body 2311 using the first fastener 25.

[0059] like Figures 1 to 7As shown, the fixed sleeve 21 has a cylindrical structure and a second through hole 212. The rotating core 221 is disposed in the second through hole 212. The extension 222 includes a collision protection plate 2221 disposed at the outer end of the rotating core 221. The collision protection structure 20 includes a sliding assembly. The sliding assembly includes an inclined sliding groove 26 and a sliding block 27 that slides with the inclined sliding groove 26. The inclined sliding groove 26 is disposed on the radial outer surface of the rotating core 221. The sliding block 27 is disposed on the radial inner wall of the second through hole 212. The inclined sliding groove 26 and the sliding block 27 slide with each other. Since the fixed sleeve 21 is fixedly connected to the box base 10, the sliding block 27 is stationary relative to the box base 10. When the rotating core 221 moves along the inner and outer directions of the box base 10, the rotating core 221 will also rotate relative to the box base 10, thereby driving the extension 222 to move between the collision protection position and the storage position. In other embodiments, a sliding block is disposed on the radial outer surface of the rotating core, and an oblique sliding groove is disposed on the radial inner wall of the second through hole.

[0060] like Figure 1 as well as Figure 4 As shown, the anti-collision structure 20 also includes a second reset member 28 disposed between the rotating core 221 and the fixed sleeve 21. The second reset member 28 applies a second reset force to the rotating core 221 to keep the protrusion 222 in the anti-collision position. When there is no external force pressing the anti-collision part 22 into the LED cabinet (for example, when two adjacent LED cabinets separate), the second reset member 28 applies a second reset force to the rotating core 221 in the direction of the outer end of the rotating core 221, so that the rotating core 221 moves in the direction of the outer end of the rotating core 221 until the locking protrusion 232 engages with the anti-rotation groove 2111 to prevent rotation. During the outward movement of the rotating core 221, it will also rotate relative to the fixed sleeve 21 and drive the protrusion 222 to switch from the storage position to the anti-collision position. That is, the setting of the second reset member 28 enables the protrusion 222 to automatically reset to the anti-collision position.

[0061] like Figure 2 , Figure 4 as well as Figure 6As shown, a first retaining ring 2219 is provided on the radial outer surface of the rotating core 221, and a second retaining ring 2121 is provided on the radial inner wall of the second through hole 212. A second reset member 28 is disposed between the radial outer surface of the rotating core 221 and the radial inner wall of the second through hole 212, with both ends of the second reset member 28 abutting against the first retaining ring 2219 and the second retaining ring 2121, respectively. In this embodiment, the second reset member 28 is a compression spring, with one end abutting against the first retaining ring 2219 and the other end abutting against the second retaining ring 2121. The compression spring applies a second reset force to the rotating core 221 in the direction of its outer end, causing the rotating core 221 to move in the direction of its outer end or to have a tendency to move in the direction of its outer end.

[0062] like Figure 8 as well as Figure 9 As shown, the anti-collision structure 20 includes a first anti-collision structure 201 and a second anti-collision structure 202. The box base 10 has a mounting side wall 100, and the first anti-collision structure 201 and the second anti-collision structure 202 are respectively provided at both ends of the mounting side wall 100. When the protrusion 222 of the first anti-collision structure 201 is in the anti-collision position, the anti-collision plate 2221 of the first anti-collision structure 201 protrudes forward and outward from the mounting side wall 100 of the box base 10. When the protrusion 222 of the second anti-collision structure 202 is in the anti-collision position, the anti-collision plate 2221 of the second anti-collision structure 202 protrudes forward and outward from the mounting side wall 100 of the box base 10.

[0063] The first anti-collision structure 201 and the second anti-collision structure 202 are respectively disposed at both ends of the mounting sidewall 100, so that the part of the LED display device close to the mounting sidewall 100 can be protected by the anti-collision structure 20. In this embodiment, the cabinet base 10 is a rectangular structure, and the cabinet base 10 includes two opposite and spaced mounting sidewalls 100. The two mounting sidewalls 100 extend in the lateral direction, and the first anti-collision structure 201 and the second anti-collision structure 202 are disposed at both ends of the two mounting sidewalls 100, so that the LED display device can avoid collisions from multiple directions, thereby making the protective function of the anti-collision structure 20 more complete. In addition, the first anti-collision structure 201 includes a first inclined sliding groove, and the second anti-collision structure 202 includes a second inclined sliding groove. The spiral direction of the first inclined sliding groove is opposite to the spiral direction of the second inclined sliding groove.

[0064] like Figures 10 to 12As shown, the fixing sleeve 21 has a cylindrical structure and a second through hole 212. The rotating core 221 is disposed within the second through hole 212. The extension 222 includes a bumper plate 2221 disposed at the outer end of the rotating core 221. A first receiving groove 11 is provided on the side wall of the housing base 10. The fixing sleeve 21 is disposed within the first receiving groove 11. The LED housing also includes a positioning assembly, which includes a positioning protrusion 12 and a positioning groove 13 that positions and cooperates with the positioning protrusion 12. The positioning protrusion 12 is disposed on the fixing sleeve 21, and the positioning groove 13 is disposed in the first receiving groove 11. The positioning groove 13 and the positioning protrusion 12 are positioned and cooperated with each other, so that the fixing sleeve 21 can be quickly installed into the first receiving groove 11 and positioned. In addition, in other embodiments, the positioning protrusion is disposed in the first receiving groove, and the positioning groove is disposed on the fixing sleeve.

[0065] like Figures 10 to 12 As shown, the side wall of the housing base 10 is also provided with a second receiving groove 14 communicating with the first receiving groove 11. The LED housing also includes a second fastener 15 disposed in the second receiving groove 14. A positioning protrusion 12 is disposed on the fixing sleeve 21, and a positioning groove 13 is disposed in the first receiving groove 11. The outer surface of the positioning protrusion 12 cooperates with the second fastener 15 to stop and restrict the fixing sleeve 21 from disengaging from the first receiving groove 11. In this embodiment, the second fastener 15 is a screw with a large head. The second receiving groove 14 and the positioning groove 13 are disposed close to each other. After the anti-collision structure 20 is installed into the first receiving groove 11, the second fastener 15 is installed into the second receiving groove 14. The large head of the screw will stop the outer surface of the positioning protrusion 12 to prevent the fixing sleeve 21 from coming out of the first receiving groove 11. In addition, in other embodiments, the outer end face of the fixing sleeve can also cooperate with the second fastener to stop and restrict the fixing sleeve from disengaging from the first receiving groove.

[0066] like Figure 1 , Figure 3 , Figure 7 , Figure 11 as well as Figure 12As shown, the fixing sleeve 21 includes a first arc-shaped plate 213 and a second arc-shaped plate 214. The first arc-shaped plate 213 has a first protruding edge 2131 on both sides, and the second arc-shaped plate 214 has a second protruding edge 2141 on both sides. The outer surface of the positioning protrusion 12 cooperates with the stop of the second fastener 15, and the corresponding first protruding edge 2131 and second protruding edge 2141 fit together to form the positioning protrusion 12. Since the sliding block 27 is located on the radial inner wall of the second through hole 212, the rotating core 221 will interfere with the sliding block 27 when it is inserted into the second through hole 212. Therefore, the fixing sleeve 21 needs to be set as a split structure. After the first arc plate 213 and the second arc plate 214 are combined, the first protruding edge 2131 and the second protruding edge 2141 can be combined to form the positioning protrusion 12. At this time, after the combined positioning protrusion 12 is placed into the positioning groove 13, the second fastener 15 is installed into the second receiving groove 14. The large head of the screw can stop both the first protruding edge 2131 and the second protruding edge 2141, so as to eliminate the structure of fixing the first arc plate 213 and the second arc plate 214 together.

[0067] like Figure 1 , Figure 3 , Figure 7 , Figure 11 as well as Figure 12 As shown, a third receiving groove 16 is also provided on the side wall of the box base 10. The third receiving groove 16 extends forward through the box base 10. The first receiving groove 11 and the second receiving groove 14 are both provided on the bottom wall of the third receiving groove 16. The outer end of the second fastener 15 is lower than or flush with the bottom wall of the third receiving groove 16. When the protrusion 222 is in the retracted position, the anti-collision plate 2221 is completely retracted into the third receiving groove 16. The third receiving groove 16 is used to receive the anti-collision plate 2221. The outer end of the second fastener 15 is lower than or flush with the bottom wall of the third receiving groove 16 so that when the protrusion 222 switches between the anti-collision position and the retracted position, the anti-collision plate 2221 will not interfere with the second fastener 15.

[0068] It should be noted that the above-mentioned "completely concealed" means that the anti-collision plate 2221 neither protrudes forward nor outward from the box base 10.

[0069] like Figure 13 as well as Figure 14As shown, the cabinet base 10 includes two opposing and spaced-apart mounting sidewalls 100, which extend laterally. Each end of the two mounting sidewalls 100 is provided with a first anti-collision structure 201 and a second anti-collision structure 202. When the two cabinet bases 10 are stacked, the first anti-collision structures 201 and the second anti-collision structures 202 of the two cabinet bases 10 press against each other, causing the extended portion 222 to switch to a retracted position. At this time, the end face of the outer end of the extended portion 222 remains flush with the cabinet base 10, allowing the two cabinet bases 10 to fit tightly together without affecting the display effect after the two cabinet bases 10 are stacked.

[0070] Explanation of the anti-collision structure state switching during LED cabinet installation: When LED cabinets are stacked, the anti-collision structures of adjacent LED cabinets press against each other. After the locking lever 231 moves inward a certain distance, the locking member 23 switches from the locked position to the unlocked position. Continuing to press down, the protruding part 222 switches from the protective position to the retracted position. When the stacked LED cabinets are separated, the second reset member 28 applies a second outward reset force to the rotating core 221, causing the protruding part 222 to switch from the retracted position to the protective position. Then, the first reset member 24 applies a first outward reset force to the locking lever 231, causing the locking member 23 to switch from the unlocked position to the locked position.

[0071] This application also provides an LED display device, which includes an LED cabinet, wherein the LED cabinet is the aforementioned LED cabinet. The aforementioned LED cabinet effectively solves the problem in related technologies where the protective structure cannot continuously maintain a protective state, and the LED cabinet having the aforementioned LED cabinet also has the aforementioned advantages.
