DETAILED DESCRIPTION

[0025] 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. 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.

[0026] like Figures 1 to 4 As shown, a novel anti-folding and collision-resistant LED display screen includes:

[0027] Mounting base 1 is made of high-strength aluminum alloy and precision-cast. Its flat bottom provides sufficient area to ensure stability when the display screen is placed. Specially designed casters 2 are installed at the four bottom corners. These casters are made of rubber with a polyurethane outer layer; the rubber layer provides excellent grip and shock absorption, while the polyurethane core ensures strength and wear resistance. Lifting rods 3 are fixedly installed on both sides of the upper part of mounting base 1. These lifting rods 3 use an electro-hydraulic structure with a stroke range of 0.5 meters to 1.5 meters, allowing for precise adjustment of the LED main screen's height. The lifting rods can be easily controlled to rise, fall, and stop via a remote control or the control panel on the base. When used in a conference room, the main screen height can be adjusted to the optimal position according to different table and chair heights and viewing angles, enhancing the user's viewing experience.

[0028] The lifting push rod 3 connects to the LED main screen 4; the LED main screen body 401 is composed of standard LED modules spliced ​​together, with the modules connected by high-precision slots and buckles to ensure a tight and flat splicing. Behind the LED main screen body 401 is an LED main screen housing 402, which is assembled onto the LED main screen body 401. The LED main screen housing 402 is made of metal, manufactured through stamping and bending processes, and has good strength and heat dissipation performance. The two sides of the LED main screen body protrude from the LED main screen housing with a first protruding edge 403; its width is 2 cm. Figure 3 and 4As shown, the LED main screen shell 402 behind the first convex edge 403 forms a first recess 404. Two LED side screens 5 are connected to the two sides of the LED main screen 4, and the LED side screen 5 includes an LED side screen body 501 and an LED side screen shell 502. The LED side screen body 501 is also composed of an LED module and is assembled with the LED side screen shell 502. The LED side screen body 501 opposite to the LED side screen shell 502 assembled with the LED main screen 4 protrudes a second convex edge 503, and the size of the second convex edge 503 is 2 cm. The LED side screen shell 502 behind the second convex edge 503 is provided with a second recess 504. Ten pairs of N52 grade neodymium iron boron magnets 6 are uniformly arranged at the corresponding positions in the first recess 404 and the second recess 504. The magnets 6 are pasted on the bottom of the recess by strong glue, and the magnetic pole directions of the magnets 6 are opposite to each other, so as to ensure that enough attractive force is generated when the screen is unfolded, and the first convex edge 403 and the second convex edge 503 of the side screen and the main screen are automatically calibrated and closely attached, thereby greatly improving the integrity and continuity of the display picture.

[0029] A connecting shaft 7 is arranged between the LED main screen shell 402 and the LED side screen shell 502, and a plurality of groups of multi-stage damping hinges 8 are sleeved on the connecting shaft 7. The sleeves of the multi-stage damping hinges 8 are connected to the LED main screen shell 402 and the LED side screen shell 502 on the two sides, respectively. The connecting shaft 7 is made of stainless steel, and has a diameter of 10 mm and a polished surface to reduce friction. The sleeves of the multi-stage damping hinges 8 are firmly connected to the LED main screen shell 402 and the LED side screen shell 502 on the two sides by welding or bolt connection. The damping sheets inside the multi-stage damping hinges 8 generate damping effect during the folding and unfolding of the side screen, effectively buffering the impact force of the rapid movement of the side screen, so that the side screen can move smoothly and slowly to the position.

[0030] Silicone cushions 9 are arranged in the first recess 404 and the second recess 504, respectively. The silicone cushions 9 are made of food-grade silicone material and have good elasticity and aging resistance. The silicone cushions 9 are respectively laid outside the N52 grade neodymium iron boron magnets 6, and the outer side of the silicone cushions 9 protrudes 2 mm from the corresponding side of the LED main screen body 401. During the unfolding of the screen body, the silicone cushions 9 can effectively absorb the impact force generated by the mechanical movement again, avoid the screen body directly colliding with the connecting member to cause scratches or damage, effectively prolong the service life of the appearance of the display screen, and reduce the noise generated by the collision.

[0031] In other specific embodiments, as Figure 1 and 2As shown, the mounting base 1 corresponding to the lower bottom of the LED main screen 4 is provided with a limit sensor 10, which adopts infrared induction principle. When the main screen is lowered to the lowest safe position, the sensor sends a signal to stop the lowering action of the lifting push rod 2, preventing the main screen from being damaged due to excessive lowering.

[0032] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
