However, this kind of artificial fall will inevitably result in the bracket not being laid flat or being affected by wind resistance, causing the bracket to fall to the ground with one side or one corner of the bracket landing first. This will result in different experimental results each time / each person doing the experiment, and the technical problem of large errors.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A LED bracket drop test device comprises a base plate for placing the LED bracket, a guide assembly arranged above the base plate, and a supporting assembly sliding along the guide assembly, the supporting assembly comprising a sliding portion slidably connected to the guide assembly, a supporting plate rotatably connected to the sliding portion, and a supporting rod rotatably connected to the sliding portion, the supporting plate is used to place a pressure plate, the sliding portion is connected to the supporting rod by an elastic member, the supporting rod has a supporting end and a swinging end arranged oppositely, when the elastic member is reset, the supporting end abuts against the supporting plate so that the supporting plate is placed horizontally, a toggle assembly for toggling the swinging end is provided below the supporting assembly, when the support rod moves downward, the swinging end contacts the toggle assembly, and the support rod rotates to make the supporting end detach from the supporting plate.

[0007] According to one aspect of the above technical solution, the base plate is rectangular, and the guide assembly includes angle steels and guide rods fixed to the four corners of the base plate, and the guide rods are located on a side of the angle steels close to the base plate.

[0008] According to one aspect of the above technical solution, the sliding part is slidably connected to the guide rod, a sliding block is provided on a side of the sliding part close to the angle steel, and a sliding groove corresponding to the sliding block is provided on the angle steel.

[0009] According to one aspect of the above technical solution, the supporting plate and the sliding part are rotationally connected via a first rotating shaft.

[0010] According to one aspect of the above technical solution, the support rod and the sliding part are rotationally connected via a second rotating shaft, and the elastic member is a torsion spring.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] See also Figures 1 to 4 , shown is an LED bracket drop test device in an embodiment of the utility model, characterized in that it includes a base plate 10 for placing the LED bracket, a guide assembly 20 arranged above the base plate 10, and a supporting assembly 30 sliding along the guide assembly 20, the supporting assembly 30 includes a sliding portion 31 slidably connected to the guide assembly 20, a supporting plate 33 rotatably connected to the sliding portion 31, and a supporting rod 35 rotatably connected to the sliding portion 31, the supporting plate 33 is used to place a pressing plate 40, the sliding portion 31 is connected to the supporting rod 35 by an elastic member, the supporting rod 35 has a supporting end and a swinging end arranged oppositely, when the elastic member is reset, the supporting end abuts against the supporting plate 33, so that the supporting plate 33 is placed horizontally, and a toggle assembly 50 for toggling the swinging end is provided below the supporting assembly 30, when the supporting rod 35 moves downward, the swinging end contacts the toggle assembly 50, and the supporting rod 35 rotates to make the supporting end detach from the supporting plate 33.

[0029] It can be understood that the present invention sets a bottom plate 10, places the LED bracket on the bottom plate 10, and sets a guide assembly 20 and a supporting assembly 30 above the bottom plate 10. When the LED bracket needs to be subjected to a drop test, the pressing plate 40 is placed on the groove supporting plate 33. At this time, the elastic member is in a reset state, and the supporting end of the support rod 35 abuts against the supporting plate 33 to keep it horizontal. After the sliding part 31 slides along the guide assembly 20 to a corresponding height, the sliding part 31 is released, and the supporting part will carry the pressing plate 40. The support rod 35 slides downward along the guide assembly 20. When the support rod 35 is about to reach the bottom plate 10, the swing end contacts the toggle assembly 50, driving the support rod 35 to rotate, so that the support end is separated from the support plate 33 and no longer supports the support plate 33. The support plate 33 will rotate downward and no longer carry the pressing plate 40. The pressing plate 40 will fall freely and contact the LED bracket. This design structure ensures the guiding role of the pressing plate 40 during the falling process. When it is about to reach the LED bracket, the pressing plate 40 is released to avoid the influence of the supporting assembly 30 on the experiment.

[0030] The utility model converts the active drop of the LED bracket into a passive drop, which can eliminate the influence of human and environmental factors on the LED bracket drop experiment in the prior art, making the experimental data more accurate and ensuring the yield of the LED bracket. The device can also reduce the cost of manpower and time, has a wide applicability, and will not affect the progress of the experiment due to changes in the site.

[0031] Specifically, the base plate 10 is rectangular in shape, and the guide assembly 20 includes an angle steel 21 and a guide rod 22 fixed to the four corners of the base plate 10, and the guide rod 22 is located on a side of the angle steel 21 close to the base plate 10; the sliding portion 31 is slidably connected to the guide rod 22, and a slider 38 is provided on a side of the sliding portion 31 close to the angle steel 21, and a sliding groove 23 corresponding to the slider 38 is provided on the angle steel 21.

[0032] It can be understood that in order to ensure the smooth descent of the sliding part 31, two layers of guiding measures are adopted. When the sliding part 31 moves in the guide rod 22, the stability of the sliding part 31 in the vertical direction can be guaranteed, and the setting of the slider 38 and the slide groove 23 can ensure that the sliding part 31 will not rotate in the horizontal direction when sliding.

[0033] More specifically, the supporting plate 33 is rotatably connected to the sliding portion 31 via a first rotating shaft 32 ; the supporting rod 35 is rotatably connected to the sliding portion 31 via a second rotating shaft 36 , and the elastic member is a torsion spring 37 .

[0034] It should be noted that when the torsion spring 37 is in the reset state, the support end rests against the bottom of the support plate 33 and needs to bear the gravity of the support plate 33 and the pressure plate 40 at the same time, and the second rotating shaft 36 will not rotate, thereby ensuring the stability of the pressure plate 40 placed on the support plate 33.

[0035] Preferably, the toggle assembly 50 includes a mounting block 51 fixedly connected to the angle steel 21, and a toggle rod 52 fixedly connected to the mounting block 51, and the toggle rod 52 is used to contact the support rod 35; a blocking block 24 is also provided at one end of the angle steel 21 close to the base plate 10, and the blocking block 24 is used to limit the descent of the sliding part 31.

[0036] It should be noted that when the sliding portion 31 contacts the blocking block 24, the swing end of the support rod 35 is still in contact with the toggle rod 52 to prevent the support rod 35 from continuing to descend and disengaging from the toggle rod 52 when the pressure plate 40 has not completely fallen. The torsion spring 37 resets and drives the support rod 35 to rest against the support plate 33 again.

[0037] Furthermore, the upper surface of each supporting plate 33 close to one end is provided with a first placement groove 11, and the pressing plate 40 is placed in the first placement groove 11 of each supporting plate 33; the upper surface of the base plate 10 is recessed to form a second placement groove 34, and the LED bracket is placed in the second placement groove 34.

[0038] It can be understood that the first placement groove 11 and the second placement groove 34 can respectively ensure that the LED bracket and the pressure plate 40 are placed in the correct position so that the experiment can proceed normally. At the same time, the second placement groove 34 has a certain limiting effect on the pressure plate 40 in the horizontal direction to prevent the pressure plate 40 from shaking horizontally when falling.

[0039] In summary, the LED bracket drop test device in the above-mentioned embodiment of the utility model converts the active drop of the LED bracket into a passive drop, which can eliminate the influence of human and environmental factors on the LED bracket drop test in the prior art, making the experimental data more accurate and ensuring the yield of the LED bracket. The device can reduce the cost of manpower and time, has a wide applicability, and will not affect the progress of the experiment due to changes in the site.
