Description

Technical Field

[0001] The present invention relates to the technical field of anti-collision protection, and in particular to an anti-collision protection mechanism and an LED unit module device. Background Art

[0002] In real life, small-pitch LED unit modules are directly installed on fixed rods, and then multiple small-pitch LED unit modules are assembled into LED display screens through locking mechanisms. However, small-pitch LED unit modules are protected by packaging boxes and built-in foam fixing brackets or bubble films during transportation. When the packaging box is opened and exposed or during the screen assembly process, the edges of the small-pitch LED unit modules are not protected. The assemblers can only rely on their personal attention and vigilance to avoid damaging the small-pitch LED unit modules, because the lamp beads of the small-pitch LED unit modules are close to the edge of the module and are extremely susceptible to bumps and collisions. In addition, the lamp bead soldering pads of the small-pitch LED unit modules are small and have low adhesion. They are easily damaged after bumps and collisions, and the loss cost is too high. In order to prevent damage from bumps and collisions, the installation is very cautious, and the installation efficiency is too low. Summary of the invention

[0014] Figure 2 It is a structural schematic diagram of the LED unit module device of the present invention. DETAILED DESCRIPTION

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1 and Figure 2As shown, the anti-collision protection mechanism of the present invention includes a base 1, a telescopic device 2 and a protection plate 3, and a mounting hole 11 is provided on the base 1; wherein the telescopic device 2 includes a guide rod 21 and a thin plate spring 22, and a trigger block 23 is provided at one end of the guide rod 21, and the first end of the thin plate spring 22 is fixedly set at the connection between the trigger block 23 and the guide rod 21 and extends in the radial direction of the guide rod 21, and a return spring 24 is sleeved on the guide rod 21, and the guide rod 21 and the return spring 24 are set in the mounting hole 11; the second end of the thin plate spring 22 is connected to the protection plate 3. When in use, the trigger block 23 moves downward when receiving external force, overcoming the elastic force of the reset spring 24, driving the guide rod 21 and the first end of the thin plate spring 22 to move downward, and at this time, the second end of the thin plate spring 22 retracts toward the trigger block 23, thereby driving the protection plate 3 to retract inward. If an object to be protected is provided on the side wall of the base 1, such as a small-pitch LED unit module 8, when the thin plate spring 22 is in a natural state, the protection plate 3 protects the edge of the small-pitch LED unit module 8; when the thin plate spring 22 is in a retracted state, the edge of the small-pitch LED unit module 8 is in an open state, which facilitates the docking and assembly of the edges of two small-pitch LED unit modules 8.

[0017] A guide pin 4 is provided on the base 1 to facilitate positioning and guiding, and more accurate installation. The thin plate spring sheet 22 has two pieces, which are symmetrically arranged on both sides of the guide rod 21, respectively, so as to protect both sides. Preferably, the two thin plate spring sheets 22 are an integral structure, and an inclined surface is arranged between the first end and the second end of the thin plate spring sheet 22, and the second end is arranged in a direction away from the guide rod 21. The inclined surface is more conducive to the retraction. A fixing hole 5 is provided at the second end of the thin plate spring sheet 22 to facilitate the installation of the protection plate 3.

[0018] An LED unit module device of the present invention includes an anti-collision protection mechanism, and also includes a fixing rod 6, an assembly hole 7 is provided on the side of the fixing rod 6, an LED unit module 8 is provided on the assembly hole 7, the edge of the LED unit module 8 protrudes from the surface of the fixing rod 6 to form a storage groove, at least two anti-collision protection mechanisms are provided on the surface of the fixing rod 6, and the base 1 is arranged on the surface of the fixing rod 6. Preferably, the base 1 and the fixing rod 6 are set as an integral structure. When in use, the LED unit module 8 is first installed on the assembly hole 7, and the two LED unit module devices are close to each other, and approach along the direction of the guide pin 4 under the action of external force, and begin to assemble into a large screen. When the protection plates 3 on both sides are about to contact, the trigger block 23 is triggered, driving the thin plate spring 22 and the protection plate 3 to start to move closer and retract. When the screen bodies on both sides are completely assembled together, the protection plate 3 has also completely fallen into the storage groove and hidden behind the LED unit module 8; when the screen body is disassembled, the above action will be reversed, and the module protection plate 3 will eventually return to its original position to play the role of the protection module.

[0019] The above is a specific implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
