Description

Technical Field

[0001] This utility model relates to the field of power adapter board technology, and in particular to a power adapter board with improved structure. Background Technology

[0002] Power adapter boards, as key components for powering electronic devices, are widely used in industrial control, communication equipment, consumer electronics, and other fields. Their main function is to adapt and convert different power interfaces or voltage specifications. As electronic devices develop towards higher power density and miniaturization, power adapter boards are prone to performance degradation due to poor heat dissipation during long-term operation. In fact, dust accumulation can also affect heat dissipation efficiency and shorten service life. Therefore, there is an urgent need for a power adapter board with an improved structure that can ensure efficient heat dissipation, optimize installation methods, and improve the reliability and maintenance convenience of the equipment.

[0003] Currently, common power adapter board cooling solutions mainly rely on heat dissipation fins combined with natural convection or forced air cooling to dissipate heat. However, they lack filtration devices, allowing external dust and debris to easily enter the equipment with the airflow. In terms of installation and fixation, most adapter boards are directly screwed onto the chassis or equipment frame. While these methods can achieve basic functions, they still have certain limitations in long-term use.

[0004] However, the above solutions still have obvious defects in practical applications. Due to the lack of effective dust filtration and convenient cleaning mechanisms, dust drawn in during heat dissipation is prone to accumulate on the surface of electrical components, which not only affects heat dissipation efficiency, but also leads to component aging or even short circuits after long-term use, seriously shortening the service life of the equipment. At the same time, the complicated installation process and unstable fixing method also greatly reduce the user experience and cannot meet the actual needs of quick installation and flexible disassembly. Therefore, a structurally improved power adapter board is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a power adapter board with improved structure, which aims to improve the problem of dust easily entering the device and causing poor heat dissipation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An improved power adapter board includes a power adapter, a fixing plate is fixedly connected to the rear side of the outer wall of the power adapter, and a filter assembly is disposed inside the fixing plate.

[0008] The filter assembly includes a filter plate, the outer wall of which is slidably connected to the inside of a fixed plate. A handle is fixedly connected to one side of the filter plate, and symmetrical locking blocks are fixedly connected to the other side of the filter plate. Each locking block has a locking box on its side, the outer wall of which is fixedly connected to the inside of the fixed plate. The outer walls of the locking blocks are slidably connected to the inside of the locking boxes. Limiting balls are provided on both the upper and lower sides of the locking blocks. Limiting plates are fixedly connected to the side walls of the limiting balls. The outer walls of the limiting plates and the limiting balls are slidably connected to the inside of the locking boxes. Limiting springs are provided on the side walls of the limiting plates. One end of each limiting spring is fixedly connected to the inside of the locking box, and the other end is fixedly connected to the side wall of the limiting plates.

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

[0010] The power adapter has a heat dissipation vent on the front side of its outer wall, which is used to expel hot air from inside the power adapter.

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

[0012] A power input port is fixedly connected to the left side of the outer wall of the power adapter. The power input port is used to connect the input power cord to provide power to the device.

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

[0014] A power output port is fixedly connected to the right side of the outer wall of the power adapter. The power output port is used to output converted electrical energy.

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

[0016] The power adapter is fixedly connected to a support plate at its bottom. Locking posts are slidably connected to the four corners of the support plate. Multiple ball bearings are slidably connected to the bottom of the locking posts. The ball bearings are distributed in a circumferential shape. A limit ring is fixedly connected to the top of the locking posts.

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

[0018] The inner wall of each locking column is slidably connected to a movable column, the bottom of the outer wall of each movable column is provided with a limit groove, the top of each movable column is fixedly connected to a linkage column, and the top of each linkage column is fixedly connected to a rotating handle.

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

[0020] A limit block is fixedly connected to the bottom of the outer wall of the linkage column. The limit block is distributed in a circular shape, and a reset spring is provided at the bottom of the linkage column.

[0021] As a further description of the above technical solution:

[0022] One end of each reset spring is fixedly connected inside the locking post, and the other end of each reset spring is fixedly connected to the bottom of the linkage post.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the heat dissipation device draws in outside air from one side, filters it through the filter plate, and discharges it from the heat dissipation port on the other side to cool the internal electrical components. When cleaning the filter plate, pull the handle to slide the filter plate outward, and it can be removed for cleaning. When installing, the locking block is inserted into the locking box, and the limiting spring pushes the limiting plate into the recess of the locking block to fix it.

[0025] 2. In this utility model, the locking pin is first inserted into the mounting hole. The handle is pressed down to move the linkage pin and the outer wall limit block downwards, so that the limit block passes through the limit ring and compresses the reset spring. At the same time, the movable pin and the limit groove are moved downwards, and the ball slides out from the limit groove and is locked into the mounting hole to complete the fixation. This achieves the effect of quickly fixing the power adapter board, solving the problem of cumbersome and time-consuming traditional installation, and improving installation efficiency and fixation stability.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4 The present invention provides an embodiment of a power adapter board with improved structure, including a power adapter 1. The power adapter 1 is the core component, consisting of an engineering plastic shell and an internal circuit board. The shell has insulating and flame-retardant properties, and the internal components integrate electrical components such as transformers and rectifiers to realize the conversion and transmission of power supply voltage. The power adapter 1 is prior art and will not be described in detail here. A fixing plate 5 is fixedly connected to the rear side of the outer wall of the power adapter 1 by bolts. The fixing plate 5 is made of aluminum alloy and is used to install filter components and provide structural support for the power adapter 1. The fixing plate 5 is equipped with filter components inside.

[0035] The filter assembly includes a filter plate 6, the main body of which consists of a metal frame and a filter medium. The metal frame is made of stainless steel, and the filter medium is made of fiber filter media for filtering dust and impurities from the air. The outer wall of the filter plate 6 is slidably connected to the inside of the fixed plate 5. A handle 7 is fixedly connected to one side of the filter plate 6. The handle 7 is made of engineering plastic and has anti-slip textures on the surface for easy operation. A pair of symmetrical locking blocks 9 are fixedly connected to the other side of the filter plate 6. The locking blocks 9 are made of metal and have recessed grooves on both sides. A locking box 10, made of metal, is provided inside to provide sliding space for the locking block 9. The outer walls of the locking box 10 are fixedly connected to the inside of the fixing plate 5, and the outer walls of the locking block 9 are slidably connected to the inside of the locking box 10. Limiting balls 13 are provided on the upper and lower sides of the locking block 9 to engage with the recessed grooves of the locking block 9, thereby limiting the displacement of the filter plate 6. Limiting plates 12 are fixedly connected to the side walls of the limiting balls 13 to transmit the elastic force of the limiting spring 11 and limit the displacement of the limiting balls 13. The outer walls of the limiting plates 12 and the limiting balls 13 are slidably connected to the locking box 10. Inside the locking box 10, limit springs 11 are provided on the side walls of the limiting plate 12. The limit springs 11 are made of spring steel, with one end fixedly connected to the inside of the locking box 10 and the other end fixedly connected to the side wall of the limiting plate 12. These springs provide a restoring force to engage the limiting ball 13 with the recess of the locking block 9. A heat dissipation vent 8 is provided on the front side of the outer wall of the power adapter 1 to expel the heat generated by the internal electrical components during operation, maintaining the normal operating temperature of the equipment. A power supply is fixedly connected to the left side of the outer wall of the power adapter 1. Inlet 3, power input port 3 is used to connect the input power cord to provide power to the equipment. Power output port 4 is fixedly connected to the right side of the outer wall of the power adapter 1. Power output port 4 is used to output the converted power. Power input port 3 and power output port 4 are existing technologies and will not be described in detail here. Support plate 2 is fixedly connected to the bottom of the power adapter 1. Support plate 2 is made of engineering plastic. Locking posts 14 are slidably connected to the four corners of the support plate 2. Locking posts 14 are made of metal and are used to fix the power adapter plate to the equipment frame or mounting surface.

[0036] Specifically, during daily use of this structurally improved power adapter board, the internal heat dissipation device of the power adapter 1 is activated, generating negative pressure to draw in outside air from one side of the power adapter 1. The outside air first passes through the filter plate 6 inside the fixed plate 5. The filter screen of the filter plate 6 uses physical interception and adsorption to isolate dust, hair, and other debris from the air. Clean air enters the power adapter 1, flows over the heating electrical components, and is cooled through heat conduction and convection, finally being discharged from the heat dissipation port 8. When cleaning is required... When the filter plate 6 is in operation, the operator holds the handle 7 and applies outward pulling force. The handle 7 causes the filter plate 6 to slide outward in a straight line along the sliding track inside the fixed plate 5. The displacement of the filter plate 6 causes the locking block 9 on its side wall to move outward from inside the locking box 10. After the outer wall of the locking block 9 contacts the limiting ball 13 inside the locking box 10, it applies lateral pressure to the limiting ball 13. Under the action of pressure, the limiting ball 13 slides into the locking box 10, while pushing the limiting plate 12 to compress the limiting spring 11. When the locking block 9 is completely disengaged from the locking box... After 10, the filter plate 6 loses its limiting constraint, and the operator can completely remove the filter plate 6 from the fixing plate 5. The filter screen of the filter plate 6 is then cleaned using a brush or water. After cleaning, the operator aligns the filter plate 6 with the inlet of the fixing plate 5 and applies a pushing force inward. The filter plate 6 slides linearly inward along the sliding track inside the fixing plate 5, and the locking block 9 on its side wall gradually inserts into the locking box 10. During the insertion of the locking block 9, the outer wall again presses against the limiting balls 13 on both sides, causing the limiting balls 13 to slide into the locking box 10. The limiting spring 11 is compressed. When the locking block 9 slides to the preset position, the recesses on both sides of the locking block 9 move to the corresponding positions of the limiting ball 13. The limiting spring 11 releases the stored elastic potential energy, pushing the limiting plate 12 and the limiting ball 13 to reset towards the locking block 9. The limiting ball 13 is inserted into the recesses on both sides of the locking block 9 to achieve mechanical locking of the filter plate 6. This completes the quick disassembly and installation of the filter plate 6, effectively preventing external dust from entering the power adapter 1 and ensuring the heat dissipation efficiency of the equipment and the service life of electrical components.

[0037] Reference Figure 5Multiple ball bearings 15, made of stainless steel and arranged in a circular pattern, are slidably connected to the bottom of the locking post 14 to achieve mechanical locking by engaging with the mounting holes. A limiting ring 21, made of metal and circular in shape, is fixedly connected to the top of the locking post 14. The inner wall of the limiting ring 21 has a groove that matches the limiting block 20, limiting the displacement of the limiting block 20 and providing a locking fulcrum. Movable posts 16 are slidably connected to the inner wall of the locking post 14. A limiting groove 17 is formed at the bottom of the outer wall of each movable post 16, matching the shape of the ball bearings 15 to accommodate them and guide their extension or retraction. A linkage post 1 is fixedly connected to the top of each movable post 16. 8. A handle 19 is fixedly connected to the top of the linkage column 18. The handle 19 is made of engineering plastic and has anti-slip texture on the surface for easy operation by the staff. A limit block 20 made of metal is fixedly connected to the bottom of the outer wall of the linkage column 18. It is used to cooperate with the limit ring 21 to lock the position of the movable column 16. The limit blocks 20 are distributed in a circumferential shape. A return spring 22 is provided at the bottom of the linkage column 18. The return spring 22 is made of spring steel. One end of the return spring 22 is fixedly connected to the inside of the locking column 14, and the other end of the return spring 22 is fixedly connected to the bottom of the linkage column 18. It is used to provide a return force after the staff releases the handle 19 to keep the linkage column 18 in the locked position.

[0038] Specifically, when installing the power adapter board with the improved structure, the worker first aligns the holes at the four corners of the support plate 2 with the corresponding holes on the equipment frame or mounting surface, and inserts the bottom of the locking post 14 into the hole at the installation position. At this time, the ball bearing 15 inside the locking post 14 is located inside the limiting groove 17 and does not contact the installation hole. Then, the worker holds the handle 19 and presses it down. The downward displacement of the handle 19 causes the linkage column 18 and multiple limiting blocks 20 on its outer wall to move downward linearly in sync. During this downward movement, the limiting blocks 20 pass through the internal space of the limiting ring 21, at which point the return spring 22 is compressed. Simultaneously, the downward displacement of the linkage column 18 causes the movable column 16 and the limiting groove 17 to move downward. At this time, the ball 15 slides outward from inside the limiting groove 17, and the outer wall of the ball 15 contacts the inner wall of the mounting hole and engages in the groove of the hole, achieving initial positioning. Next, the operator rotates the handle 19 clockwise or counterclockwise by 45°. The rotation of the handle 19 is transmitted to the limiting blocks 20 through the linkage column 18, causing the limiting blocks 20 to move downward relative to the linkage column 18. The axis rotates in a circle. After the limiting block 20 rotates, it is no longer aligned with the slot of the limiting ring 21. The bottom of the limiting ring 21 forms a vertical constraint on the limiting block 20, preventing the linkage column 18 from moving upward, thereby fixing the position of the movable column 16 and keeping the ball 15 in the state of being inserted into the mounting hole. The bearing plate 2 is quickly fixed to the mounting plane through the locking column 14. The entire process is controlled by pressing and rotating the handle 19 to control the movement of the linkage column 18, the movable column 16 and the ball 15. The locking state is maintained by the cooperation of the return spring 22 and the limiting ring 21. Installation can be completed without tools, which significantly improves the installation efficiency of the power adapter board.

[0039] Working principle: When installing the improved power adapter board, first align the holes at the four corners of the support plate 2 with the desired installation position. Then, insert the bottom of the locking pin 14 into the hole at the installation position. Next, press down the handle 19. The displacement of the handle 19 first causes the linkage pin 18 and multiple limit blocks 20 on its outer wall to move downward, allowing the limit blocks 20 to pass through the limit ring 21 and compress the return spring 22. At the same time, it also causes the movable pin 16 and the limit groove 17 to move downward, and the ball 15 slides out from inside the limit groove 17. Its outer wall is then inserted into the installation hole. Then, rotate the handle 19 by 45°. The handle 19 causes the linkage pin 18 and the limit blocks 20 on its outer wall to rotate by 45°. The rotation of the limit blocks 20 causes them to be locked below the limit ring 21, thus fixing the position of the movable pin 16 and fixing the position of the ball 15. This completes the fixing of the support plate 2, achieving the effect of quickly fixing the power adapter board.

[0040] When using the improved power adapter board in daily use, the heat dissipation device inside the power adapter 1 draws outside air into the device from one side and exhausts it from the heat dissipation vent 8 on the other side. The outside air first passes through the filter plate 6 inside the fixed plate 5 to isolate dust and debris before entering the device to cool the internal electrical components. When the filter plate 6 needs to be cleaned, the operator first manually pulls the handle 7 outward. The displacement of the handle 7 causes the filter plate 6 to slide outward, and the displacement of the filter plate 6 causes the locking block 9 on its side wall to disengage from the locking box. Once the filter plate 6 is removed from the locking box 10, the staff can remove it and clean it. Then, the staff will reinsert the cleaned filter plate 6 into the fixing plate 5. At this time, the locking block 9 will first be inserted into the locking box 10. Its outer wall will press the limit balls 13 on both sides, causing the limit balls 13 to drive the limit plate 12 into the locking box 10 and press the limit spring 11. When the locking block 9 is in place, the limit spring 11 will push the limit plate 12 back into the recesses on both sides of the locking block 9, thus completing the fixation of the filter plate 6 and effectively isolating external dust from affecting the internal heat dissipation of the equipment.
