Description

Technical Field

[0001] This utility model relates to the field of vibration testing technology, and in particular to a vibration testing device for LED lamps. Background Technology

[0002] As a widely used electric light source product, the reliability and durability of LED lights are directly related to their safety and lifespan. During transportation, installation and operation, LED lights will inevitably be subjected to vibration and impact from different directions. Therefore, conducting vibration tests on LED lights in the production process to simulate real-world environments is a key means of verifying their structural stability, solder joint quality and overall reliability.

[0003] Currently, existing vibration testing devices have the following limitations. First, many devices use a single vibration source, which can only achieve vibration in one direction and cannot effectively simulate the multi-directional and complex vibration environment in the real world, resulting in incomplete and inaccurate test results. Second, some devices lack an efficient energy buffering system, and the vibration energy is directly transferred to the device frame. Long-term use can easily lead to fatigue damage to the device structure itself, and also affect the stability of the test waveform. In addition, the fixing method of the test fixture is often relatively simple, which may pose a risk of loosening under continuous vibration, and the device lacks the necessary locking mechanism for moving parts when not in operation, which poses a safety hazard.

[0004] Therefore, it is necessary to design an LED lighting vibration testing device to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of vibration testing, such as its single direction and lack of effective buffering and protection, the technical problem of this utility model is to provide a vibration testing device for LED lamps.

[0006] The technical implementation scheme of this utility model is as follows: an LED lamp vibration testing device, comprising a mounting base, a mounting frame, first guide posts, a moving frame, first springs, limiting posts, sliders, second springs, a vibration platform, and a vibration motor. The mounting frame is fixedly connected to the top of the mounting base. Multiple first guide posts are symmetrically slidably connected to the front and back of the mounting frame. Multiple first guide posts are symmetrically slidably connected to the left, right, front, and back of the mounting frame. A moving frame is fixedly connected between all the first guide posts. Multiple first springs are connected between the moving frame and the mounting frame, and each first guide post is wound with a first spring. Multiple limiting posts are fixedly connected in a rectangular array inside the moving frame. A slider is slidably connected between the multiple limiting posts. Multiple second springs are connected between the top of the slider and the upper part of the moving frame, and each limiting post is wound with a second spring. Square through holes are opened on the upper and lower sides of the moving frame, and the two square through holes are perpendicular to each other. A vibration platform is fixedly connected to the top of the slider. A vibration motor is fixedly connected to the top and bottom of the slider, and the two vibration motors are horizontally and vertically perpendicular to each other and can pass through the nearest square through hole.

[0007] In addition, it is particularly preferred that the base also includes anti-slip pads, with multiple anti-slip pads fixedly connected in a rectangular array at the bottom.

[0008] Furthermore, preferably, it also includes a locking block, a guide tube, a sleeve, a rotating block, a locking post, and a powerful magnet. The first guide post at the front and the first guide post at the left are each provided with a circular groove at the end away from the moving frame. The lower part of each circular groove is fixedly connected to a locking block on the side away from the moving frame. A guide tube is fitted onto the end of each first guide post with a circular groove away from the moving frame. The side of the guide tube near the moving frame is fixedly connected to the outside of the mounting frame. A sleeve is slidably connected to each guide tube. A rotating block is rotatably connected to the end of each sleeve away from the moving frame. A locking post is fixedly connected to the side of each rotating block near the moving frame. A powerful magnet is fixedly connected to the end of each guide tube with a groove away from the moving frame.

[0009] In addition, it is particularly preferred that the test box and the protective cover are also included, with the test box fixedly connected to the top of the vibration platform, the protective cover slidably connected to the upper part of the test box, and a slot opened at the rear of the protective cover.

[0010] Furthermore, it is particularly preferred that the test box also includes a second guide post, a locking block, a third spring, and a push block. A square groove is provided at the rear of the test box, and multiple smaller circular grooves are symmetrically provided at the bottom of the square groove. A second guide post is slidably connected to each of the multiple smaller circular grooves. A locking block is fixedly connected between the tops of all the second guide posts. A third spring is connected between the locking block and the bottom of the square groove. Two rectangular grooves are provided at the rear of the test box, and a push block is slidably connected between all the rectangular grooves. The bottom of the push block is fixedly connected to the top of the locking block.

[0011] Furthermore, it is particularly preferred that the sliding part of the sleeve on the guide tube is made of metal.

[0012] Beneficial effects: 1. This utility model uses two vibration motors with mutually horizontal and perpendicular vibration directions, and fixes them directly to the slider to generate a composite multi-directional excitation force. This excitation force is directly transmitted to the test box and internal lamps through the vibration platform, thereby effectively simulating multi-directional and complex vibration conditions in real environment and overcoming the limitations of traditional single-direction vibration testing.

[0013] 2. This utility model comprises a multi-stage spring system consisting of a primary buffer composed of a limiting post and a second spring, and a secondary buffer composed of a first guide post and a first spring. This system can fully absorb and buffer the high-frequency impact energy generated by vibration, ensuring that the vibration process is stable and controlled. It not only achieves the vibration intensity required for testing but also effectively protects the main structure of the device and extends the service life of the equipment.

[0014] 3. This utility model, through the setting of a locking mechanism consisting of a locking block, a third spring, and a push block, can automatically and securely lock the protective cover onto the test box using spring force, effectively preventing accidental opening due to vibration during testing. Simultaneously, the cooperation of the sleeve, locking post, and powerful magnet achieves rapid locking of the first guide post, facilitating equipment transportation and maintenance, and significantly improving operational safety and stability.

[0024] Example: A vibration testing device for LED lamps, such as Figures 1-4 As shown, the system includes a mounting base 1, a mounting frame 2, first guide posts 3, a moving frame 4, a first spring 5, a limiting post 6, a slider 7, a second spring 8, a vibration platform 9, and a vibration motor 10. The mounting frame 2 is welded to the top of the mounting base 1. Two first guide posts 3 are symmetrically slidably connected to the front and rear sides of the mounting frame 2. Two more first guide posts 3 are symmetrically slidably connected to the left and right sides of the mounting frame 2. A moving frame 4 is welded between the eight first guide posts 3. Eight first springs 5 ​​connect the moving frame 4 to the mounting frame 2, and each first guide post 3 has a first spring 5 wound around it. Spring 5, four limiting posts 6 are welded in a rectangular array on the inner side of the motion frame 4, and sliders 7 are slidably connected between the four limiting posts 6. Four second springs 8 are connected between the top of the slider 7 and the upper part of the motion frame 4, and each limiting post 6 is wound with a second spring 8. Square through holes are opened on the upper and lower sides of the motion frame 4, and the two square through holes are perpendicular to each other. A vibration platform 9 is installed on the top of the slider 7 by bolts. A vibration motor 10 is installed on the top and bottom of the slider 7 by bolts, and the two vibration motors 10 are horizontal and perpendicular to each other and can pass through the nearest square through hole respectively.

[0025] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, it also includes a test box 17 and a protective cover 18. The test box 17 is bolted to the top of the vibration platform 9. The protective cover 18 is slidably connected to the upper part of the test box 17. A slot is provided on the lower rear side of the protective cover 18.

[0026] like Figure 1 , Figure 6 and Figure 7As shown, it also includes a second guide post 19, a locking block 20, a third spring 21, and a push block 22. A square groove is provided on the upper rear side of the test box 17. Two smaller circular grooves are symmetrically provided on the bottom of the square groove. A second guide post 19 is slidably connected to each of the two smaller circular grooves. A locking block 20 is glued between the tops of the two second guide posts 19. A third spring 21 is connected between the locking block 20 and the bottom of the square groove. Two rectangular grooves are symmetrically provided on the upper rear side of the test box 17. A push block 22 is slidably connected between the two rectangular grooves. The bottom of the push block 22 is glued to the top of the locking block 20.

[0027] When using this device, the operator first needs to pull the protective cover 18 forward, then securely install the LED lamp to be tested in the test box 17 on the top of the vibration platform 9, and then push the protective cover 18 backward. The rear end of the protective cover 18 pushes the locking block 20, causing the locking block 20 to compress the third spring 21 and move downward under the guidance of the second guide post 19. The locking block 20 slides into the slot along the bottom of the protective cover 18, thereby automatically locking the protective cover 18 and ensuring that the lamp will not accidentally fall out during the test. At this time, the vibration motor 10 can be started for testing. The vibration core of the device is achieved by the coordinated work of two vibration motors 10. When they are started at the same time, a compound, multi-directional excitation force will be generated. The excitation force is directly transmitted to the vibration platform 9, which is fixedly connected to the slider 7, thereby driving the test box 17 and the LED lights on it to enter the vibration state. During the vibration transmission and buffering process, the multi-stage spring system of the device plays a key role. The slider 7, which directly bears the vibration, slides under the guidance of the four limit posts 6, while stretching or compressing the second springs 8 wrapped around the limit posts 6. These second springs 8 not only transmit the vibration, but also effectively absorb and buffer high-frequency impacts, preventing them from being directly transmitted to the main structure. Then, the vibration energy continues to be transmitted outward through the motion frame 4. The motion frame 4 is slidably connected to the mounting frame 2 through eight first guide posts 3, and uses eight first springs 5 ​​wrapped around the first guide posts 3 for secondary buffering and support. This system ensures that the vibration energy is fully and controllably released and absorbed, making the entire vibration process stable and meeting the test requirements, while protecting the main structure of the device from excessive impact.

[0028] like Figure 1 and Figure 2 As shown, it also includes anti-slip pads 101. The bottom of the mounting base 1 has four anti-slip pads 101 glued together in a rectangular array.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, it also includes a locking block 11, a guide tube 12, a sleeve 13, a rotating block 14, a locking post 15, and a powerful magnet 16. The first guide post 3 on the front left and the first guide post 3 on the left front are both provided with circular grooves at the ends away from the moving frame 4. The lower part of the two circular grooves away from the moving frame 4 is glued with a locking block 11. The ends of the two first guide posts 3 with circular grooves away from the moving frame 4 are each fitted with a guide tube 12. The side of the guide tube 12 near the moving frame 4 is welded to the outside of the mounting frame 2. The sleeve 13 is slidably connected to the two guide tubes 12. The ends of the two sleeves 13 away from the moving frame 4 are rotatably connected with a rotating block 14. The side of the two rotating blocks 14 near the moving frame 4 is glued with a locking post 15. The sliding grooves on the two guide tubes 12 away from the moving frame 4 are glued with a powerful magnet 16. The sliding part of the sleeve 13 on the guide tube 12 is made of metal.

[0030] After the test is completed, the vibration motor 10 is turned off. Under the elastic restoring force of the first spring 5 and the second spring 8, the moving frame 4, the slider 7, and the vibration platform 9 will gradually stop vibrating and return to their initial equilibrium positions. In addition, this device is designed with a locking mechanism that is easy to maintain. When needed, the operator can push the sleeve 13 towards the side closer to the moving frame 4, allowing it to slide on the guide tube 12, and use the rotating block 14 to adjust the angle of the locking pin 15. Finally, the locking pin 15 is inserted into the circular groove at the end of the first guide pin 3 and locked by the locking block 11. The sleeve 13 is made of metal and can be attracted by the strong magnet 16 at the end of the guide tube 12, thereby fixing the relative position of the first guide pin 3 and the mounting frame 2, effectively preventing accidental movement during maintenance and improving the safety of the equipment.
