[0031] 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.

[0032] like Figures 1 to 9 As shown, an embodiment of the utility model provides an LED display device, which includes a box body 10, an LED module, a control box 20 and an ejection mechanism 30. The LED module is arranged on the front side of the box body 10; the control box 20 is arranged on the rear side of the box body 10, and the control box 20 and the LED module are electrically connected; the ejection mechanism 30 is arranged between the box body 10 and the control box 20, and the ejection mechanism 30 includes an ejection member movably arranged on the box body 10, and the ejection member has an initial state separated from the control box 20 and an ejection state of pushing back against the control box 20. When the ejection member is in the ejection state, the ejection member pushes against the control box 20 and moves in a direction away from the LED module.

[0033] By applying the technical solution of the utility model, the LED display device includes a box body 10, an LED module, a control box 20 and an ejection mechanism 30. When the control box 20 needs to be removed, the ejection member provided on the box body 10 is moved from the initial state separated from the control box 20 to the ejection state of the control box 20 being pushed backward, and the control box 20 can be pushed by the ejection member to move in a direction away from the LED module, so that the plug-in member of the control box 20 and the plug-in member of the LED module are separated, so that the control box 20 can be removed from the box body 10. Compared with the method of directly manually removing the control box 20, the utility model has the advantages of saving time and labor.

[0034] It should be noted that the ejector can be movably arranged on the box body 10. Including the following situations, in one embodiment, the ejector can rotate relative to the box body 10, and a protrusion 311 capable of fitting with the control box 20 is arranged on the ejector, and the rotation of the ejector is used to switch the ejector from the initial state to the ejection state to abut the control box 20. In another embodiment, the ejector can move in the front-to-back direction relative to the box body 10, and the movement of the ejector is used to abut the control box 20.

[0035] Of course, as long as the ejector can contact the control box 20 and provide the control box 20 with an ejection force in the front-to-back direction, it will suffice.

[0036] like Figure 2 and Figure 4As shown, in this embodiment, the ejector includes a rotating rod 31 rotatably disposed on the box body 10, the rotating axis of the rotating rod 31 is parallel to the display surface of the LED module, and a protrusion 311 is provided on the side wall of the rotating rod 31. When the rotating rod 31 rotates, the protrusion 311 can abut against the control box 20. By rotating the rotating rod 31, the protrusion 311 contacts and abuts against the control box 20, so as to remove the control box 20, which has the advantages of simple structure and easy operation.

[0037] Specifically, the rotation axis of the rotating rod 31 is parallel to the extension direction of the control box 20. Two protrusions 311 are arranged at intervals on the rotation axis of the rotating rod 31. Both protrusions 311 can fit with the control box 20 to make the force on the control box 20 more uniform and the movement more stable.

[0038] like Figure 2 and Figure 4 As shown, the ejection mechanism 30 also includes a locking assembly 32, which is disposed between the box body 10 and the rotating rod 31 and can stop the rotating rod 31. The locking assembly 32 is used to stop the rotating rod 31, which can prevent the rotating rod 31 from rotating accidentally, so as to avoid the control box 20 being accidentally disconnected from the LED module during the operation of the LED display device, so that the operation of the LED display device is more stable.

[0039] like Figures 6 to 8 As shown, the locking assembly 32 includes a locking rod 321 and a locking groove 322 provided on the box body 10. The locking rod 321 is movably provided on the rotating rod 31. The locking rod 321 has a locking state in which it is inserted into the locking groove 322 and an unlocking state in which it is released from the locking groove 322. When the locking rod 321 is in the locking state, the locking rod 321 stops the rotating rod 31 from rotating. When the locking rod 321 is in the unlocking state, the rotating rod 31 can rotate so that the protrusion 311 abuts against the control box 20. The locking assembly 32 with the above structure forms a locking state by the locking rod 321 and the locking groove 322 to stop the rotating rod 31 from rotating, and has the advantages of simple structure and easy operation.

[0040] The locking rod 321 is movably disposed on the rotating rod 31, including the following cases. In one embodiment, the locking rod 321 can move in a straight line relative to the rotating rod 31, and the locking rod 321 is moved in a straight line and inserted into the locking groove 322 to prevent the rotating rod 31 from rotating. In another embodiment, the locking rod 321 can rotate relative to the rotating rod 31, and the rotating locking rod 321 is inserted into the locking groove 322 after rotation to prevent the rotating rod 31 from rotating.

[0041] like Figure 5 and Figure 7As shown, the locking assembly 32 includes a locking ring 323 also provided on the box body 10, the locking ring 323 is sleeved on the outer periphery of the rotating rod 31, and the locking groove 322 is provided on the outer wall of the locking ring 323. By providing the locking groove 322 on the locking ring 323, the structure is simple and easy to process.

[0042] In this embodiment, the locking ring 323 is connected to the box body 10 by screws, thereby facilitating the processing of the locking groove 322 and the removal of the locking ring 323 .

[0043] In other embodiments, the locking groove 322 may be directly disposed on the box body 10 , and the locking ring 323 is not required.

[0044] like Figure 7 and Figure 8 As shown, the locking rod 321 is hingedly connected to the rotating rod 31, the rotation axis of the locking rod 321 is parallel to the rotation axis of the rotating rod 31, and the locking rod 321 has a locking tooth 3211. When the locking rod 321 is in the locked state, the locking tooth 3211 is inserted into the locking groove 322, and when the locking rod 321 is in the unlocked state, the locking tooth 3211 is separated from the locking groove 322. With the above structure, when the locking rod 321 is in the unlocked state, the locking tooth 3211 on the locking rod 321 is separated from the locking groove 322. At this time, the rotating rod 31 can rotate and the protrusion 311 can be used to press against the control box 20. By rotating the locking rod 321 and switching the locking rod 321 from the unlocked state to the locked state, the locking tooth 3211 can be inserted into the locking groove 322, so that the locking rod 321 cannot move relative to the locking ring 323, thereby preventing the rotating rod 31 from rotating.

[0045] like Figure 7 and Figure 8 As shown, the rotating rod 31 includes a rod body 312 and a handle 313 connected to the rod body 312 and rotating synchronously, the rotating axis of the rod body 312 is parallel to the display surface of the LED module, the protrusion 311 is arranged on the rod body 312, and the locking rod 321 is hingedly connected to the handle 313. The rotating rod 31 with the above structure can realize the rotation of the rod body 312 by operating the handle 313, which has the advantages of simple structure and easy operation.

[0046] In other embodiments, a hinge seat may be provided on the side wall of the rotating rod 31 , and the locking rod 321 may be hingedly provided on the hinge seat, so that the rotation state of the rotating rod 31 can be adjusted without providing the handle 313 .

[0047] like Figure 7As shown, the ejection mechanism 30 further includes a spring 33. The locking teeth 3211 and the spring 33 are respectively located on both sides of the rotation axis of the locking rod 321. The two ends of the spring 33 are respectively connected to the locking rod 321 and the rotating rod 31. The spring 33 can keep the locking rod 321 in the locked state. The spring 33 can provide a restoring force for the locking rod 321, so that the locking rod 321 automatically switches from the unlocked state to the locked state, thereby preventing the rotating rod 31 from rotating accidentally.

[0048] In this embodiment, a receiving groove is provided on the handle 313, the locking rod 321 is hingedly provided in the receiving groove, and the spring 33 is provided in the receiving groove. The handle 313 is also provided with an avoidance groove, the avoidance groove is connected with the receiving groove, the locking ring 323 extends into the avoidance groove, and the locking groove 322 of the locking ring 323 is provided corresponding to the locking tooth 3211.

[0049] like Figure 1 and Figure 2 As shown, the box 10 has a mounting groove 11, a through hole and an avoidance hole 12, the avoidance hole 12 is located at one end of the mounting groove 11, the mounting groove 11 is connected to the avoidance hole 12 through the through hole, the rod body 312 is arranged in the mounting groove 11 and is located between the box 10 and the control box 20, the control box 20 is arranged at the mounting groove 11, the handle 313 is located in the avoidance hole 12, and the end of the rod body 312 passes through the through hole into the avoidance hole 12 and is connected to the handle 313. With the above structure, by using the mounting groove 11, there can be enough space between the box 10 and the control box 20 for arranging the rod body 312. By using the avoidance hole 12, space can be reserved for the arrangement of the handle 313.

[0050] In this embodiment, the control box 20 is disposed at the mounting groove 11 and can avoid the avoidance hole 12 to facilitate the rotation of the handle 313 .

[0051] like Fig. 9 As shown, an ejector rib 21 is provided on the inner side wall of the control box 20. When the ejector is in the ejection state, the ejector fits with the ejector rib 21. By fitting the ejector with the ejector rib 21, direct contact between the ejector and the HUB board of the control box 20 can be avoided, thereby preventing damage to the HUB board.

[0052] In this embodiment, the front surface of the ejector rib 21 is higher than the surface of the HUB plate.

[0053] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
