Description

Technical Field

[0001] The utility model relates to the technical field of LED power supplies, in particular to an LED power supply with a buffer protection structure. Background Art

[0002] An LED power supply is an electronic device used to provide power for LED lamps. It converts alternating current (AC) into direct current (DC) to provide stable current and voltage for the LED lamps, ensuring the normal operation of the LED lamps. The LED power supply plays a crucial role in the LED lighting system because LED lamps have high requirements for the power supply and must maintain the stability of current and voltage to prevent damage to the LED lamps due to current or voltage fluctuations. Voltage fluctuations and instantaneous high-voltage spikes (such as lightning strikes, switching of power equipment, etc.) in the power grid may damage the LED power supply and its load. The buffer protection structure can absorb and relieve these instantaneous high voltages to protect the circuit and the LED lamps from damage.

[0003] Traditional LED power supplies with buffer protection structures use rubber materials for buffering to protect internal components from physical shock and vibration. In the design, key electronic components are usually wrapped with rubber materials, and rubber pads or rubber support structures are also designed inside the power supply base and the housing. Rubber materials can effectively absorb and disperse external impact forces, reduce resonance phenomena, protect the circuits and components inside the power supply, extend the service life of the components, and ensure the stability and reliability of the LED power supply. However, buffering with a single rubber does not consider the problem that the structural method is relatively single and not stable enough. For this reason, an LED power supply with a buffer protection structure is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an LED power supply with a buffer protection structure, aiming to improve the problem of insufficient stability of buffering with a single rubber in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An LED power supply with a buffer protection structure includes a housing and an LED power supply body. The LED power supply body is arranged on the top of the housing. A fixed frame is fixedly connected inside the housing. A sliding rod is fixedly connected inside the fixed frame. A slider is slidably connected to the side wall of the sliding rod, and the side wall of the slider is slidably connected inside the fixed frame. A first spring is sleeved on the side wall of the sliding rod. One end of the first spring is fixedly connected to the side wall of the slider, and the other end of the first spring is fixedly connected to the side wall of the fixed frame. A rotating column is rotatably connected to the side wall of the slider, and a rotating plate is fixedly connected to the side wall of the rotating column. A fixed block is fixedly connected to the lower surface of the LED power supply body, and a connecting column is fixedly connected between the fixed blocks. One side of the rotating plate is rotatably connected to the side wall of the connecting column. An installation plate is fixedly connected to the lower surface of the LED power supply body, and a damper is fixedly connected to the lower surface of the installation plate. The output end of the damper is fixedly connected to a fixing plate, and the side wall of the fixing plate is fixedly connected inside the housing. An auxiliary component is arranged between the fixing plate and the installation plate, and the auxiliary component is used to assist the damper in buffering work;

[0007] As a further description of the above technical solution:

[0008] The auxiliary component includes a rubber column. One end of the rubber column is fixedly connected to the upper surface of the fixing plate, and the other end of the rubber column is fixedly connected to the lower surface of the installation plate;

[0009] As a further description of the above technical solution:

[0010] Corner pads are fixedly connected to the side wall of the housing, and heat dissipation grooves are formed in the side wall of the housing;

[0011] As a further description of the above technical solution:

[0012] A filter screen is fixedly connected inside the housing, and the filter screen covers the inner side of the heat dissipation groove;

[0013] As a further description of the above technical solution:

[0014] A groove is formed inside the housing, a limiting plate is arranged on the top of the housing, a clamping block is fixedly connected to the side wall of the limiting plate, a limiting hole is formed inside the clamping block, and the side wall of the clamping block is slidably connected inside the groove;

[0015] As a further description of the above technical solution:

[0016] A sleeve is fixedly connected to the side wall of the housing, a first convex block is fixedly connected inside the sleeve, a sliding plate is slidably connected inside the sleeve, and a second convex block is fixedly connected to the side wall of the sliding plate;

[0017] As a further description of the above technical solution:

[0018] A second spring is sleeved on the side wall of the second bump and the side wall of the first bump. One end of the second spring is fixedly connected to the side wall of the sliding plate, and the other end of the second spring is fixedly connected to the inside of the sleeve.

[0019] As a further description of the above technical solution:

[0020] A limiting block is fixedly connected to the side wall of the sliding plate. The side wall of the limiting block is slidably connected to the inside of the limiting hole, and the side wall of the limiting block is slidably connected to the inside of the sleeve.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, when the LED power supply body vibrates, it slides inside the housing, causing the rotating plate to rotate on the connecting column and the slider, pushing the slider to move and causing the first spring to contract. The vibration force is transferred to the inside of the damper, and the damper and the rubber column jointly relieve and weaken the vibration force, achieving a buffering effect. This solves the problem that the buffering and protection structure of some traditional LED power supplies only buffers through rubber materials, and the structure is single and unstable. The buffering effect of the device is improved through the above technical solution.

[0023] 2. In the utility model, the clamping block on the limiting plate is inserted into the groove. During this process, the clamping block pushes the limiting block to move into the sleeve, deforming the second spring. When the limiting hole moves beside the limiting block, the second spring resets, pushing the sliding plate to move, so that the limiting block is stuck in the limiting hole to fix the limiting plate. The effect of rapid assembly is achieved, and the installation efficiency of the device is improved through the above technical solution. Description of the Drawings

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1 - 3 , an embodiment provided by the present invention: An LED power supply with a buffer protection structure includes a housing 1 and an LED power supply body 2. The LED power supply body 2 is arranged on the top of the housing 1. A fixed frame 3 is fixedly connected inside the housing 1. A slide bar 4 is fixedly connected inside the fixed frame 3. A slide block 5 is slidably connected to the side wall of the slide bar 4. The side wall of the slide block 5 is slidably connected inside the fixed frame 3. A first spring 6 is sleeved on the side wall of the slide bar 4. One end of the first spring 6 is fixedly connected to the side wall of the slide block 5, and the other end of the first spring 6 is fixedly connected to the side wall of the fixed frame 3. A rotating column 7 is rotatably connected to the side wall of the slide block 5. A rotating plate 8 is fixedly connected to the side wall of the rotating column 7. A fixed block 9 is fixedly connected to the lower surface of the LED power supply body 2. A connecting column 10 is fixedly connected between the fixed blocks 9. One side of the rotating plate 8 is rotatably connected to the side wall of the connecting column 10. A mounting plate 13 is fixedly connected to the lower surface of the LED power supply body 2. A damper 12 is fixedly connected to the lower surface of the mounting plate 13. The output end of the damper 12 is fixedly connected to a fixed plate 11. The side wall of the fixed plate 11 is fixedly connected inside the housing 1. An auxiliary component is arranged between the fixed plate 11 and the mounting plate 13. The auxiliary component is used to assist the damper 12 in buffering work. The auxiliary component includes a rubber column 14. One end of the rubber column 14 is fixedly connected to the upper surface of the fixed plate 11, and the other end of the rubber column 14 is fixedly connected to the lower surface of the mounting plate 13;

[0033] When the LED power supply body 2 vibrates, the vibration will cause the LED power supply body 2 to slide inside the housing 1. During the sliding process, one side of the rotating plate 8 will rotate on the connecting column 10, and the other side of the rotating plate 8 will rotate on the slider 5 at this time, while pushing the slider 5 to move to both sides, so that the first spring 6 contracts. When the slider 5 slides to both sides, the distance between the lower surface of the LED power supply body 2 and the inner bottom surface of the housing 1 will be reduced. In this reduction process, the force generated by the vibration is transferred to the inside of the damper 12, and the damper 12 will relieve and weaken the force generated by the vibration. At the same time, the rubber column 14 will absorb part of the force to assist the damper 12 in relieving the force generated by the vibration. In this way, the buffering effect can be achieved.

[0034] Refer to Figures 4 - 5 , a corner pad 15 is fixedly connected to the side wall of the housing 1, a heat dissipation groove 16 is opened on the side wall of the housing 1, a filter screen 17 is fixedly connected inside the housing 1, the filter screen 17 covers the inner side of the heat dissipation groove 16, a groove 18 is opened inside the housing 1, a limiting plate 19 is arranged on the top of the housing 1, a clamping block 20 is fixedly connected to the side wall of the limiting plate 19, a limiting hole 21 is opened inside the clamping block 20, the side wall of the clamping block 20 is slidably connected inside the groove 18, a sleeve 22 is fixedly connected to the side wall of the housing 1, a first convex block 23 is fixedly connected inside the sleeve 22, a sliding plate 24 is slidably connected inside the sleeve 22, a second convex block 25 is fixedly connected to the side wall of the sliding plate 24, a second spring 27 is sleeved on the side walls of the second convex block 25 and the first convex block 23, one end of the second spring 27 is fixedly connected to the side wall of the sliding plate 24, the other end of the second spring 27 is fixedly connected inside the sleeve 22, a limiting block 26 is fixedly connected to the side wall of the sliding plate 24, the side wall of the limiting block 26 is slidably connected inside the limiting hole 21, and the side wall of the limiting block 26 is slidably connected inside the sleeve 22.

[0035] Slowly insert the clamping block 20 at the bottom of the limiting plate 19 into the inside of the groove 18. During the insertion process, the clamping block 20 will exert a certain pressure on the limiting block 26, causing the limiting block 26 to move. With the application of pressure, the limiting block 26 will be pushed to move inside the sleeve 22, so that the second spring 27 deforms. When the limiting hole 21 moves to one side of the limiting block 26, the second spring 27 will lose pressure at this time and thus reset, while pushing the sliding plate 24 to move. The movement of the sliding plate 24 clamps the limiting block 26 inside the limiting hole 21, so that the limiting plate 19 can be fixed. The fixing of the limiting plate 19 restricts the LED power supply body 2 to prevent the LED power supply body 2 from detaching from the inside of the housing 1, thus completing the installation. The heat dissipation groove 16 opened on the side wall of the housing 1 can dissipate the heat inside the housing 1, and the filter screen 17 can prevent dust from entering the inside of the housing 1 during the heat dissipation process.

[0036] Working principle: When the LED power supply body 2 vibrates, it will slide inside the housing 1, causing one side of the rotating plate 8 to rotate on the connecting column 10. The other side of the rotating plate 8 will rotate on the slider 5 while pushing the slider 5 to both sides and causing the first spring 6 to contract. When the slider 5 slides to both sides, the distance between the lower surface of the LED power supply body 2 and the inner bottom surface of the housing 1 will decrease, thereby transferring the force generated by the vibration to the inside of the damper 12. The damper 12 will relieve and weaken the force generated by the vibration. At the same time, the rubber column 14 will absorb part of the force and assist the damper 12 in relieving the force generated by the vibration, so as to achieve the buffering effect. Insert the block 20 at the bottom of the limiting plate 19 into the groove 18. During the insertion process, the block 20 will apply pressure to the limiting block 26 and push the limiting block 26 into the inside of the sleeve 22, causing the second spring 27 to be compressed and deformed. When the limiting hole 21 moves to one side of the limiting block 26, the second spring 27 will lose pressure at this time and reset, and push the sliding plate 24 to move to lock the limiting block 26 inside the limiting hole 21 to fix the limiting plate 19. At this time, the limiting plate 19 will limit the LED power supply body 2 to prevent the LED power supply body 2 from detaching from the inside of the housing 1, thus completing the assembly.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
