[0023] The fixing mechanism comprises a base 20, a fixing member 30 and a limiting member 40, the fixing member 30 is used for fixing the LED screen body 10 to the base 20, the limiting member 40 is detachably connected with the fixing member 30, the limiting member 40 is connected with the fixing member 30, so as to limit the LED screen body 10 to the rear window in the vehicle, that is, the LED screen body 10 is in the display state position.

[0024] The base 20 is provided with a suction cup 50, and the base 20 is fixed to the lower side of the rear window in the vehicle through the suction cup 50. The base 20 comprises a bottom plate 201, and a first side plate 202 and a second side plate 203 vertically connected to one side of the bottom plate 201. The first side plate 202 is provided with two groups of second side plates 203 in parallel at both ends. The first side plate 202 and the two groups of second side plates 203 form an accommodating groove. A connecting seat 21 is hingedly connected in the accommodating groove. The connecting seat 21 is rotationally connected with the second side plates 203 on both sides. The first side plate 202 is used for limiting and supporting the connecting seat 21. The length of the connecting seat 21 is adapted to the length of the LED screen body 10. The connecting seat 21 is provided with a groove 211 on one side. The groove 211 is adapted to the shape and size of the bottom of the LED screen body 10. The groove 211 is used for embedding the bottom of the LED screen body 10. Two groups of plug-in grooves 212 are symmetrically arranged in the groove 211. The connecting seat 21 is provided with a first through hole 213 vertically penetrating the plug-in grooves 212. The fixing member 30 adopts a U-shaped clamping structure. The fixing member 30 comprises a back plate 31, and connecting plates 32 vertically arranged on both sides of the back plate 31. The connecting plates 32 on both sides are in parallel. The connecting plates 32 are provided with second through holes 34 on the sides away from the back plate 31. The distance between the connecting plates 32 on both sides is adapted to the thickness of the LED screen body 10. The LED screen body 10 is accommodated between the connecting plates 32 on both sides. The end of the connecting plate 32 is used for being inserted into the plug-in groove 212. The first through hole 213 is aligned with the second through hole 34 and is fixed by a bolt. At this time, the bottom of the LED screen body 10 is embedded in the groove 211. The LED screen body 10 is fixed to the connecting seat 21 through the fixing member 30. In a natural state, i.e. a non-display state position, the connecting seat 21 abuts against the first side plate 202. The LED screen body 10 is located below one side of the rear window in the vehicle. It is convenient for the driver to observe the road conditions behind the vehicle through the rearview mirror and the rear window.

[0025] The limiting piece 40 is provided with a suction cup 50 on one side, and the limiting piece 40 is fixed to the rear window in the vehicle through the suction cup 50. The other side of the limiting piece 40 is provided with a limiting groove 41 and a limiting member. The limiting member includes a limiting rod 42 penetrating the limiting piece 40. The limiting rod 42 has a first end 421 and a second end 422. The first end 421 penetrates the limiting groove 41, and the second end 422 penetrates out of the limiting piece 40. A hand holding part is arranged at the second end 422. The limiting piece 40 is provided with a cavity 401. The limiting rod 42 penetrates the cavity 401. The limiting rod 42 in the cavity 401 is sleeved with a spring 424. The limiting rod 42 at one end of the spring 424 is provided with an annular baffle 423. The other end of the spring 424 abuts against the inner wall of the cavity 401. Under the action of the spring 424, the first end 421 of the limiting rod 42 is located in the limiting groove 41. The first end 421 is inclined towards one side of the slot of the limiting groove 41. One side of the fixing piece 30 is provided with a limiting protrusion 33. The limiting protrusion 33 is connected with the fixing piece 30 through a connecting rod. The cross-sectional size of the connecting rod is smaller than that of the limiting protrusion 33. One end of the limiting protrusion 33 close to the connecting rod is a plane, and the other end away from the connecting rod is a curved surface. Under the action of an external force, the limiting protrusion 33 abuts against the first end 421 of the limiting rod 42. The curved surface cooperates with the inclined surface to compress the spring 424. The limiting protrusion 33 penetrates into the limiting groove 41. After the spring 424 recovers, the limiting protrusion 33 is limited by the first end 421, so as to connect the fixing piece 30 and the limiting piece 40. That is, the LED screen body 10 is in a display state position. The LED screen body 10 is located on one side of the rear window in the vehicle, so as to facilitate the rear vehicle to observe the display content of the LED screen body 10.

[0026] In one embodiment, one side of the fixing piece 30 is provided with a support rod 35. One end of the support rod 35 is hinged with the end of the side connecting plate 32. The connecting plate 32 is provided with a PVC pipe clamp 36 for clamping the support rod 35, so as to facilitate the storage of the support rod 35. The support rod 35 is used for auxiliary support of the fixing piece 30, so as to assist in supporting the LED screen body 10 in a non-display state. The support rod 35 and the limiting protrusion 33 are respectively arranged on the two side connecting plates 32.

[0027] The end of the support rod 35 can be provided with a suction cup 50, which is adsorbed to the bottom surface of the trunk in the vehicle through the suction cup 50, so as to improve the stability of the support.

[0028] In one embodiment, the inner side of the fixing piece 30 is provided with a cushion layer 37. The cushion layer 37 can be sponge, which avoids the hard contact between the fixing piece 30 and the LED screen body 10, and helps to reduce the abrasion generated by disassembly and assembly of the LED screen body 10.

[0029] When the LED tail warning screen device is used, i.e. when road maintenance work is needed, the fixing part 30 is turned over, the limiting protrusion 33 is inserted into the limiting groove 41 and fixed, the LED screen body 10 is arranged at the rear window position in the vehicle, and the road maintenance work is displayed on the LED screen body 10 to prompt the driving vehicle to avoid.

[0030] When non-road maintenance work is needed, the limiting rod 42 is pulled, the spring 424 is compressed through the annular baffle 423, the limiting protrusion 33 is separated from the limiting groove 41, the LED screen body 10 is turned over, the supporting rod 35 is unfolded, the bottom of the supporting rod 35 is abutted with the bottom surface of the trunk in the vehicle, and the LED screen body 10 is supported.

[0031] When the LED screen body 10 needs to be disassembled, the bolt between the fixing part 30 and the connecting seat 21 is removed, the fixing part 30 and the connecting seat 21 are quickly separated, and the LED screen body 10 is quickly disassembled and assembled.

[0032] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
