Description

Technical Field

[0001] This utility model relates to the field of driver power supply technology, and in particular to a waterproof and dustproof structure for LED driver power supply. Background Technology

[0002] An LED driver is a power converter that transforms a power supply into a specific voltage and current to drive an LED to emit light. With the widespread application of LED lighting technology, the importance of LED drivers in various lighting systems is becoming increasingly prominent. In particular, in outdoor lighting, industrial lighting, and other environments, LED drivers face severe challenges in terms of waterproofing and dustproofing.

[0003] In traditional LED driver power supplies, moisture and dust can easily penetrate the interior of the LED driver power supply in outdoor or humid and dusty environments, which can seriously affect its performance and lifespan. Therefore, protective shells are often used to waterproof and dustproof it. However, existing protective shells not only have complicated connection methods, but also affect the heat dissipation performance of the power supply, leading to overheating and reduced lifespan. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing waterproof and dustproof structure of LED driver power supply has the disadvantages of being cumbersome to operate and affecting the heat dissipation of the power supply. Therefore, we propose a waterproof and dustproof structure for LED driver power supply.

[0005] To achieve the above objectives, this application adopts the following technical solution: a waterproof and dustproof structure for an LED driver power supply, comprising a base plate, a mounting seat on the top of the base plate, a power supply body mounted on the top of the mounting seat, a housing fixed to the outside of the mounting seat on the top of the base plate, a protective shell mounted on the top of the housing, fixing blocks fixed to both sides of the protective shell, housings fixed to both sides of the housing seat, a push rod slidably connected to the side wall of the housing, a protrusion fixed to one end of the push rod inside the housing, fixing plates with spring-loaded mechanisms slidably connected to both sides inside the housing, a force-bearing block fixed to one side of the fixing plate, the opposite surface of the force-bearing block abutting against both sides of the protrusion, a locking block fixed to the top of the fixing plate, and locking grooves for cooperating with the locking blocks on both sides of the fixing block.

[0006] Preferably, the rebound mechanism includes a first spring mounted on the other side of the fixed plate, the other end of which is fixed to the interior of the housing.

[0007] Preferably, limit rods are fixed on both sides inside the housing, and the surface of the fixing plate is provided with a through groove for use with the limit rods.

[0008] Preferably, the opposite surface of the force-bearing block is provided with an inclined surface, which is used in conjunction with the two sides of the protrusion.

[0009] Preferably, the surface of the mounting base and both sides of the protective shell are provided with several through holes, which can form a complete heat dissipation channel.

[0010] Preferably, the housing and protective shell are made of waterproof material.

[0011] Preferably, each of the four corners of the top of the mounting base is fixed with a positioning block, and two second springs are fixed to the inner side of the positioning block, with a clamping block fixed to the other end of the two second springs.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pressing the push rod to move it into the housing, the protrusion presses against the force-bearing block. The force-bearing block then pushes the fixing plate to press against the first spring, simultaneously causing the locking block to disengage from the slot. This allows the housing to separate from the protective shell. The operation is simple and requires no special tools, making the maintenance of the power supply body more convenient and faster, reducing maintenance costs and time. At the same time, the heat dissipation channel formed by the through holes on the protective shell and the mounting base, and the fact that the power supply body does not directly contact the base plate during use, effectively dissipates heat from the power supply body, reducing its operating temperature and improving its stability and lifespan.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a waterproof and dustproof structure for an LED driver power supply, including a base plate 1, a mounting base 2 on the top of the base plate 1, a power supply body 3 mounted on the top of the mounting base 2, a housing 4 fixed to the top of the base plate 1 outside the mounting base 2, a protective shell 5 mounted on the top of the housing 4, fixing blocks 6 fixed to both sides of the protective shell 5, and housings 7 fixed to both sides of the housing 4. A push rod 8 is slidably connected to the side wall of the housing 7, and a protrusion 9 is fixed to one end of the push rod 8 inside the housing 7. Fixing plates 10 with spring-loaded mechanisms are slidably connected to both sides inside the housing 7. A force-bearing block 11 is fixed to one side of the fixing plate 10, and the opposite surface of the force-bearing block 11 abuts against both sides of the protrusion 9. A locking block 12 is fixed to the top of the fixing plate 10, and locking blocks 12 are provided on both sides of the fixing block 6 to match the locking block 12. The mounting base 2 and the protective shell 5 are provided with several through holes on the surface of the slot 13 and both sides of the mounting base 2. These through holes can form a complete heat dissipation channel. By pressing the push rod 8 to move into the shell 7, the protrusion 9 is pressed against the force block 11. Then the force block 11 will push the fixing plate 10 to press against the first spring 16, and at the same time drive the locking block 12 to disengage from the inside of the slot 13, so that the shell base 4 can be separated from the protective shell 5. The operation is simple and does not require specific tools, which makes the maintenance of the power supply body 3 more convenient and quick, reducing maintenance costs and time. At the same time, the heat dissipation channel formed by the through holes on the protective shell 5 and the mounting base 2, and the fact that the power supply body 3 does not directly contact the base plate 1 during use, achieves effective heat dissipation of the power supply body 3, reduces the operating temperature of the power supply body 3, and improves its stability and lifespan.

[0022] Reference Figure 3 As shown, in this embodiment: the rebound mechanism includes a first spring 16 installed on the other side of the fixed plate 10. The other end of the first spring 16 is fixed to the inside of the housing 7. By setting the first spring 16, when it is necessary to reconnect the housing 4 and the protective housing 5, the fixed block 6 is reset, and the rebound force accumulated by the first spring 16 pushes the fixed plate 10 to drive the locking block 12 to insert into the inside of the locking slot 13, thereby realizing the reconnection of the housing 4 and the protective housing 5.

[0023] Reference Figure 3As shown in this embodiment: Limiting rods 14 are fixed on both sides inside the housing 7, and a through groove 15 is provided on the surface of the fixing plate 10 to cooperate with the limiting rods 14. Through the structure of the limiting rods 14 and the through groove 15, the movement trajectory of the fixing plate 10 can be restricted, so as to avoid the movement of the fixing plate 10 inside the housing 7 from being deviated and affecting the fixing effect of the fixing block 6.

[0024] Reference Figure 3 As shown in this embodiment: the opposite side of the force-bearing block 11 is provided with an inclined surface, which is used in conjunction with the two sides of the protrusion 9. By providing an inclined surface on the opposite side of the force-bearing block 11, when the protrusion 9 presses against the force-bearing block 11, the inclined surface structure makes the force-bearing block 11 easier to push. At the same time, the inclined surface structure can also automatically reset the force-bearing block 11 when the protrusion 9 is separated from the force-bearing block 11 by using the guiding effect of the inclined surface, which is convenient for the next operation.

[0025] Reference Figure 2 As shown in this embodiment, the housing 4 and the protective shell 5 are made of waterproof material. By using waterproof material for the housing 4 and the protective shell 5, it is possible to effectively prevent water from entering the interior of the power supply body 3, avoid water damage to the power supply body 3, and improve the service life of the power supply.

[0026] Reference Figure 4 - Figure 5 As shown in this embodiment: positioning blocks 17 are fixed at the four corners of the top of the mounting base 2. Two second springs 18 are fixed on the inner side of the positioning blocks 17. Clamping blocks 19 are fixed at the other end of the two second springs 18. Through the structure of the positioning blocks 17, the second springs 18 and the clamping blocks 19, the contact area of ​​the power supply body 3 can be increased, the fixation can be improved, and the power supply body 3 can be prevented from shaking or falling off during use. At the same time, the structure of the positioning blocks 17, the second springs 18 and the clamping blocks 19 is simple, easy to install and disassemble, and convenient for maintenance and replacement of the power supply body 3.

[0027] The working principle of this utility model is as follows: The user moves the push rod 8 into the housing 7, causing the protrusion 9 to press against the force block 11. The force block 11 then pushes the fixing plate 10 to press against the first spring 16, simultaneously causing the locking block 12 to disengage from the slot 13, thus separating the housing 4 from the protective housing 5. The operation is simple and requires no special tools, making the maintenance of the power supply body 3 more convenient and faster, reducing maintenance costs and time. Simultaneously, the heat dissipation channel formed by the through holes on the protective housing 5 and the mounting base 2, and the fact that the power supply body 3 does not directly contact the base plate 1 during use, effectively dissipates heat from the power supply body 3, reducing its operating temperature and improving its stability and lifespan. Due to the first spring 16, when it is necessary to reconnect the housing 4 and the protective housing 5, by resetting the fixing block 6, the accumulated rebound force of the first spring 16 pushes the fixing plate 10, causing the locking block 12 to insert into the slot 13, thus reconnecting the housing 4 and the protective housing 5. The structure of the limiting rod 14 and the through slot 15 allows for… The movement trajectory of the fixing plate 10 is restricted to prevent it from shifting inside the housing 7 and affecting the fixing effect on the fixing block 6. By opening a slope on the opposite side of the force block 11, the slope structure makes it easier to push the force block 11 when the protrusion 9 presses against it. At the same time, the slope structure can also guide the force block 11 to automatically reset when the protrusion 9 disengages from it, facilitating the next operation. By using waterproof materials for the housing 4 and the protective housing 5, water can be effectively prevented from entering the power supply body 3, avoiding damage to the power supply body 3 and improving the service life of the power supply. The structure of the positioning block 17, the second spring 18 and the clamping block 19 can increase the contact area of ​​the power supply body 3, improve the fixing firmness, and prevent the power supply body 3 from shaking or falling off during use. At the same time, the structure of the positioning block 17, the second spring 18 and the clamping block 19 is simple in design, easy to install and disassemble, and convenient for maintenance and replacement of the power supply body 3.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
