Description

Technical Field

[0001] This utility model relates to the field of LED module board technology, specifically to an impact-resistant LED module. Background Technology

[0002] LED module boards and displays are important components of modern display technology and are widely used in advertising, information display, stage backgrounds and traffic signs. An LED module board consists of multiple small light-emitting diode beads, which are arranged on a printed circuit board through precise circuit design to form a complete display unit.

[0003] According to a public notice (Announcement No.: CN118824124B) of an LED module board and display screen, the above application uses a protective screen to protect the LED module board and LED beads, uses an intelligent fan to dissipate heat from the LED module board, and uses a temperature sensor to detect the temperature of the LED module board. The speed of the intelligent fan can be adjusted according to the temperature of the LED module board detected by the temperature sensor, thereby achieving energy saving.

[0004] However, in actual use, the LED modules of the above-mentioned devices rely solely on the protective screen for protection against external impacts. Stronger impacts can easily cause the protective screen to shatter, thus affecting the LED modules behind it. In view of this, we propose an impact-resistant LED module. Utility Model Content

[0005] The purpose of this invention is to provide an impact-resistant LED module to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant LED module, comprising a support frame, a module body disposed on the inner wall of the support frame, a protective screen disposed inside the support frame, a force-relieving mechanism disposed inside the support frame, and a promoting mechanism disposed inside the support frame, the force-relieving mechanism comprising:

[0007] A rotating shaft is fixedly installed on the inner wall of the support frame. A movable plate is fixedly installed on the upper surface of the protective screen. A fixed plate is fixedly installed on the arc surface of the rotating shaft. A bending rod is fixedly installed on the surface of the fixed plate. A bending spring is fixedly installed on the surface of the fixed plate.

[0008] A limiting plate is fixedly installed on the inner wall of the support frame. The limiting plate has a movable groove on its arc surface. An arc-shaped rod is fixedly connected to the inner wall of the movable groove. A return spring is fixedly connected to the inner wall of the movable groove. A sliding block is fixedly connected to the end of the return spring away from the movable groove. A positioning plate is fixedly connected to the arc surface of the sliding block.

[0009] Preferably, the promoting mechanism includes a guide groove, which is formed on the surface of the limiting plate. A straight rod is fixedly connected to the inner wall of the guide groove. A torsion spring is fixedly connected to the arc surface of the straight rod. A swing plate is fixedly connected to the end of the torsion spring away from the arc surface of the straight rod. A roller is movably mounted on the surface of the swing plate.

[0010] Preferably, the surface of the swing plate is provided with a rotating hole, the diameter of which is adapted to the diameter of the straight rod, and the swing plate is sleeved on the arc surface of the straight rod, so that the swing plate can rotate on the arc surface of the straight rod.

[0011] Preferably, the surface of the sliding block is provided with a sliding hole, the shape of which is adapted to the shape of the arc-shaped rod, and the sliding block is sleeved on the surface of the arc-shaped rod, allowing the sliding block to slide along the arc-shaped rod.

[0012] Preferably, the end of the bending spring away from the fixed plate is fixedly connected to a movable plate, the movable plate being sleeved on the arc surface of the bending rod, and the movable plate being able to move along the bending rod.

[0013] Preferably, there are two sets of fixing plates, which are arranged in a mirror image and fixedly installed on the arc surface of the rotating shaft, so as to facilitate the installation of bending rods on the fixing plates.

[0014] Compared with the prior art, this utility model provides an impact-resistant LED module with the following advantages:

[0015] 1. This impact-resistant LED module is equipped with a force-dissipating mechanism. When the protective screen is impacted by an external object, the screen will rotate with the impacting end. During the rotation, the movable plate rotates on the arc surface of the bending rod, causing the bending spring to deform and buffer the external force on the screen. At the same time, when the screen rotates to a certain extent, the edge of the screen contacts the positioning plate, causing the positioning plate to move the sliding block on the arc surface of the curved rod. The reset spring deforms, further buffering the rotation of the screen. Then, the sliding block slides inside the movable groove to a certain extent and is limited to form an oblique angle, guiding the colliding object to one end, reducing the impact force, and further protecting the module body.

[0016] 2. This impact-resistant LED module is equipped with a promoting mechanism. One end of the protective screen contacts the limiting plate, and the other end of the protective screen deflects off the limiting plate. When the protective screen is reset, the other end of the protective screen contacts the swing plate, causing the rollers on the swing plate to contact and rotate. At the same time, the swing plate can be deflected to a certain extent by the protective screen, which better guides the protective screen into the limiting plate for the next impact protection, thus protecting the module body.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: an impact-resistant LED module, including a support frame 1, a module body 5 disposed on the inner wall of the support frame 1, a protective screen 2 disposed inside the support frame 1, a force-relieving mechanism 3 disposed inside the support frame 1, and a promoting mechanism 4 disposed inside the support frame 1. The force-relieving mechanism 3 includes a rotating shaft 301, a movable plate 302, a fixed plate 303, a bending rod 304, a bending spring 305, a limiting plate 306, a movable groove 307, an arc-shaped rod 308, a sliding block 309, a positioning plate 310, and a return spring 311.

[0024] In one embodiment of this utility model, a rotating shaft 301 is fixedly installed on the inner wall of the support frame 1, a movable plate 302 is fixedly installed on the upper surface of the protective screen 2, a fixed plate 303 is fixedly installed on the arc surface of the rotating shaft 301, a bending rod 304 is fixedly installed on the surface of the fixed plate 303, a bending spring 305 is fixedly installed on the surface of the fixed plate 303, a limiting plate 306 is fixedly installed on the inner wall of the support frame 1, a movable groove 307 is provided on the arc surface of the limiting plate 306, an arc-shaped rod 308 is fixedly connected to the inner wall of the movable groove 307, a return spring 311 is fixedly connected to the inner wall of the movable groove 307, a sliding block 309 is fixedly connected to the end of the return spring 311 away from the movable groove 307, and a positioning plate 310 is fixedly connected to the arc surface of the sliding block 309.

[0025] In addition, the promoting mechanism 4 includes a guide groove 401, which is formed on the surface of the limiting plate 306. A straight rod 402 is fixedly connected to the inner wall of the guide groove 401. A torsion spring 405 is fixedly connected to the arc surface of the straight rod 402. A swing plate 403 is fixedly connected to the end of the torsion spring 405 away from the arc surface of the straight rod 402. A roller 404 is movably mounted on the surface of the swing plate 403. A rotating hole is formed on the surface of the swing plate 403. The diameter of the rotating hole is adapted to the diameter of the straight rod 402. The swing plate 403 is sleeved on the arc surface of the straight rod 402. The swing plate 403 can rotate on the arc surface of the straight rod 402. A protrusion is provided at the opening of the guide groove 401 to limit the swing of the swing plate 403, ensuring that the protective screen 2 can contact the roller 404 on the swing plate 403 when it is reset from the outside to the inside of the support frame 1.

[0026] In an embodiment of this utility model, a sliding hole is provided on the surface of the sliding block 309. The shape of the sliding hole is adapted to the shape of the arc rod 308. The sliding block 309 is sleeved on the surface of the arc rod 308 and can slide along the arc rod 308. The end of the bending spring 305 away from the fixed plate 303 is fixedly connected to the movable plate 302. The movable plate 302 is sleeved on the arc surface of the bending rod 304 and can move along the bending rod 304. Two sets of fixed plates 303 are provided. The two sets of fixed plates 303 are arranged in a mirror image and fixedly installed on the arc surface of the rotating shaft 301 to facilitate the installation of the bending rod 304 on the fixed plate 303.

[0027] In this utility model, when the protective screen 2 is impacted by an external object, the protective screen 2 will rotate with the impacting end. During the rotation of the protective screen 2, the movable plate 302 rotates on the arc surface of the curved rod 304, causing the curved spring 305 to deform and buffer the external force on the protective screen 2. At the same time, when the protective screen 2 rotates to a certain extent, the edge of the protective screen 2 contacts the positioning plate 310, causing the positioning plate 310 to drive the sliding block 309 to move on the arc surface of the curved rod 308. The reset spring 311 deforms, further buffering the rotation of the protective screen 2. Then, the sliding block 309 slides to a certain extent inside the movable groove 307 to be limited, forming an oblique angle, guiding the colliding object to one end, reducing the impact force, and further protecting the module body 5.

[0028] Furthermore, one end of the protective screen 2 contacts the limiting plate 306, and the other end of the protective screen 2 deviates from the limiting plate 306. When the protective screen 2 is reset, the other end of the protective screen 2 contacts the swing plate 403, causing the roller 404 on the swing plate 403 to come into contact and rotate. At the same time, the swing plate 403 can be deviated to a certain extent by the protective screen 2, which better guides the protective screen 2 into the limiting plate 306 for the next impact protection, thus protecting the module body 5.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
