Description

Technical Field

[0001] This utility model relates to the field of power adapters, specifically a high-power adapter power supply with safe output voltage. Background Technology

[0002] A power adapter is an electronic device that converts external power into stable DC power required by specific devices. Its core function is to adapt and supply power. Through internal circuit design, it converts the input high-voltage AC power into low-voltage DC power usable by the device, while ensuring the stability of output voltage and current to avoid damage to the device due to voltage fluctuations or current overload. Power adapters are usually composed of modules such as input filtering circuit, rectifier circuit, switching power supply circuit, voltage regulator circuit and output protection circuit. They integrate functions such as overvoltage protection, overcurrent protection, short circuit protection and overheat protection to ensure safe use. They are widely used in consumer electronics, industrial equipment, medical instruments and communication base stations. In existing technologies, power adapters use a structural housing to securely mount high-power energy conversion components inside, and then connect to an external power source to convert and deliver current to the device in use. However, the structural housings of most existing power adapters are usually connected by bolts or other fasteners. This method of disassembly and installation is cumbersome and makes it inconvenient to inspect and maintain the internal energy conversion components. In addition, power adapters generate a lot of heat during continuous operation, and the heat is not easily dissipated, which accelerates the aging of the energy conversion components and reduces the lifespan of the power adapter. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the outer casing of most existing power adapters is usually connected by bolts or fixing methods. This method is cumbersome to disassemble and install, and it is not convenient to inspect and maintain the internal power conversion components. At the same time, the power adapter will generate a lot of heat during continuous operation. The heat is not easy to dissipate, which will accelerate the aging of the power conversion components and reduce the service life of the power adapter.

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a high-power adapter power supply with a safe output voltage. (Refer to...) Figure 1-4 A safe output voltage high-power adapter power supply includes a first hollow shell 1, a second hollow shell 2 disposed on one side of the first hollow shell 1, a power supply assembly 3 fixedly connected to the inner cavity of the first hollow shell 1, and a fixing mechanism 4 disposed on one side of the first hollow shell 1, with four fixing mechanisms 4. A heat dissipation mechanism 5 is fixedly connected to one side of both the first hollow shell 1 and the second hollow shell 2. The first hollow shell 1 and the second hollow shell 2 can cooperate to install the power supply assembly 3, providing stable protection for the power supply assembly 3 and preventing external factors from affecting its lifespan and operation. Furthermore, a hinged plate is disposed on one side of the second hollow shell 2, allowing the second hollow shell 2 to slide and connect with the first hollow shell 1, thereby achieving protective installation of the power supply assembly 3. The power supply assembly 3 is installed and fixed inside the first hollow shell 1, serving as an important internal component of the power adapter. The device can adapt and supply power in different forms, converting the input high-voltage AC power into low-voltage DC power usable by the equipment, while ensuring the stability of the output voltage and current to avoid damage to the equipment due to voltage fluctuations or current overload, thus achieving current conversion. The fixing mechanism 4 is installed on both sides of the first hollow shell 1 and the second hollow shell 2, which can be used to fix the first hollow shell 1 and the second hollow shell 2 together, thereby facilitating the subsequent installation and disassembly of the first hollow shell 1 and the second hollow shell 2, and making it convenient to inspect and maintain the power supply component 3. Two sets of heat dissipation mechanisms 5 are provided, which are respectively installed on the surface of the first hollow shell 1 and the second hollow shell 2. They can conduct the heat generated by the operation of the power supply component 3 to the outside through the heat dissipation mechanism 5, thereby achieving a good heat dissipation effect on the power supply component 3 inside the first hollow shell 1 and the second hollow shell 2, thus extending its service life.

[0017] The fixing mechanism 4 includes a first fixing shell 401, one side of which is fixedly connected to one side of a second hollow shell 2. The first hollow shell 1 is fixedly connected to a second fixing shell 402. A long rod 403 is slidably connected to the inner cavity of the first fixing shell 401. A first conical block 404 is fixedly connected to one side of the long rod 403. A second conical block 405 is slidably connected to the surface of the long rod 403. An installation groove 406 is provided in the inner cavity of the second fixing shell 402. A first spring 407 is fixedly connected to the inner cavity of the installation groove 406. A locking block 408 is provided on one side of the first conical block 404. One side of the locking block 408 is fixedly connected to one side of the first spring 407. The first fixed shell 401 and the second fixed shell 402 can be used to install other components inside the fixing mechanism 4, thereby supporting and fixing the other components. The long rod 403 is installed inside the first fixed shell 401 and can be used to support and fix the first conical block 404. At the same time, it is convenient for people to pull the first conical block 404 when using the fixing mechanism 4. The first conical block 404 and the second conical block 405 are installed on the long rod 403. The first conical block 404 can be used to cooperate with the locking block 408, thereby locking onto one side of the locking block 408 to fix the first fixed shell 401 and the second fixed shell 402, thereby assisting in fixing the first hollow shell 1 and the second hollow shell 2. When it is desired to connect the first hollow shell 1 and the second hollow shell 2, the first hollow shell 1 and the second hollow shell 402 can be fixed together. When the two hollow shells 2 are directly disassembled, the first conical block 404 can be disengaged from the locking block 408 by the second conical block 405, thereby completing the separation of the first hollow shell 1 and the second hollow shell 2. This facilitates the subsequent inspection and maintenance of the power supply component 3 inside the first hollow shell 1. The first spring 407 can assist the locking block 408 in moving and returning to its original position, thereby assisting in the locking between the locking block 408 and the first conical block 404. The locking block 408 can be used to cooperate with the first conical block 404 and the second conical block 405 to fix the first fixed shell 401 and the second fixed shell 402, thereby realizing the installation and disassembly of the first hollow shell 1 and the second hollow shell 2, which facilitates the subsequent inspection of the power supply component 3.

[0018] Reference Figure 4The heat dissipation mechanism 5 includes a hollow frame 501. One side of each hollow frame 501 is fixedly connected to one side of the first hollow shell 1 and the second hollow shell 2, respectively. A heat-conducting plate 502 is fixedly connected to the inner cavity of the hollow frame 501. A heat dissipation fin 503 is provided on one side of the heat-conducting plate 502. One side of the heat dissipation fin 503 is fixedly connected to the inner cavity of the hollow frame 501. The hollow frame 501 can be used to install the heat-conducting plate 502 and the heat dissipation fin 503. When the heat generated by the power supply component 3 during continuous operation is transferred to the surface of the first hollow shell 1 and the second hollow shell 2, it can be conducted to the heat dissipation fin 503 through the heat-conducting plate 502, and then the heat dissipation fin 503 can dissipate the heat, thereby achieving a good heat dissipation effect on the power supply component 3 in a short time, preventing the power supply component 3 from generating a large amount of heat that is difficult to dissipate and affecting the operating speed, while extending its service life.

[0019] Reference Figure 3 A fixing frame 6 is fixedly connected to one side of the long rod 403. A connecting rod 7 is rotatably connected to the inner cavity of the fixing frame 6 via a rotating shaft. The fixing frame 6 can be used to install the connecting rod 7. The connecting rod 7 can be fixed inside it via the rotating shaft, and it is convenient for the connecting rod 7 to rotate later. The connecting rod 7 can improve the practicality of the long rod 403 and make it convenient for people to manually pull the long rod 403.

[0020] Reference Figure 3 The inner cavity of the second fixed shell 402 is provided with a sliding groove 8. There are two sliding grooves 8. An L-shaped connecting plate 9 is slidably connected to the inner cavity of the sliding groove 8. One side of the L-shaped connecting plate 9 is fixedly connected to one side of the locking block 408. The sliding groove 8 can be used to install the L-shaped connecting plate 9, which facilitates the sliding of the L-shaped connecting plate 9 inside it. One end of the L-shaped connecting plate 9 is connected to the locking block 408, which can improve the stability of the locking block 408 moving up and down inside the mounting groove 406 and prevent the locking block 408 from shaking left and right.

[0021] Reference Figure 3 A plastic clip 10 is provided on the surface of the connecting rod 7. One side of the plastic clip 10 is fixedly connected to one side of the first fixing shell 401. The plastic clip 10 can be used to fix the connecting rod 7 to prevent the connecting rod 7 from moving the long rod 403 due to external factors, thereby affecting the use effect of the fixing mechanism 4.

[0022] Reference Figure 3 A first magnet block 11 is fixedly connected to one side of the first conical block 404, and a second magnet block 12 is provided on one side of the first magnet block 11. One side of the second magnet block 12 is fixedly connected to one side of the locking block 408. The first magnet block 11 and the second magnet block 12 can increase the stability of the locking between the first conical block 404 and the locking block 408, making it less likely for the first conical block 404 to detach from the locking block 408.

[0023] Reference Figure 3A second spring 13 is provided on one side of the first conical block 404. One side of the second spring 13 is fixedly connected to the inner cavity of the second fixed shell 402. The second spring 13 can assist the first conical block 404 in disengaging from the locking block 408, so that the first conical block 404 can stably disengage from the interior of the second fixed shell 402, making it convenient for people to remove the second hollow shell 2 from the first hollow shell 1.

[0024] Working principle: When using this device, the first hollow shell 1 and the second hollow shell 2 can be connected to stably protect the power supply component 3 inside. Then, the movable rod 403 moves the first conical block 404. As the first conical block 404 moves, it contacts the locking block 408. At this time, the locking block 408 is pressed by the first conical block 404 and slides upward inside the mounting groove 406, simultaneously pressing the first spring 407 above it. The first spring 407 deforms. When the first conical block 404 moves to the other side of the locking block 408, the locking block 408 no longer presses the first spring 407. The first spring 407, through its own elasticity, drives the locking block 408 downward, and the locking block 408 locks onto the first conical block 404. On one side, the first conical block 404 is fixed inside the second fixed shell 402, thereby fixing the first fixed shell 401 and the second fixed shell 402 together. At this time, the first hollow shell 1 and the second hollow shell 2 are installed and fixed by the first fixed shell 401 and the second fixed shell 402. When it is necessary to inspect and repair the power component 3 inside the first hollow shell 1, the long rod 403 can be moved into the second fixed shell 402 again. The long rod 403 drives the second conical block 405 to move. The second conical block 405 is prevented from moving by the limiting protrusion on the surface of the long rod 403, thereby squeezing the pressing block 408 and causing it to move upward, so that the conical surface of the second conical block 405 contacts the pressing block 408. After the movement is completed, the long rod 403 can be pulled again. 3. By applying downward pressure from the locking block 408, the second conical block 405 slides on the long rod 403, thus engaging with the first conical block 404. After engagement, the long rod 403 is pulled further, causing the first conical block 404 to move below the locking block 408, allowing it to disengage and release its restraint. Subsequently, the first fixed shell 401 and the second fixed shell 402 can be disassembled, thereby separating the first hollow shell 1 and the second hollow shell 2. This facilitates the inspection and maintenance of the power supply assembly 3. Simultaneously, when the power supply assembly 3 continuously generates a large amount of heat that dissipates to the surfaces of the first hollow shell 1 and the second hollow shell 2, the heat can be conducted through the heat-conducting plate 502 installed inside the hollow frame 501, thereby transferring the heat to the heat dissipation fins 503. The surface of the heat sink fins 503 dissipates heat to the outside, thereby achieving a heat dissipation effect on the power supply component 3 and extending its service life. Specifically, the first fixed shell 401 and the second fixed shell 402 can be fixed together by the engagement between the first conical block 404 and the locking block 408, thus connecting and installing the first hollow shell 1 and the second hollow shell 2. This improves the practicality of the power distribution unit composed of the first hollow shell 1, the second hollow shell 2, and the power supply component 3. When it is necessary to inspect or repair the power supply component 3, the locking block 408 can be disengaged from the first conical block 404 by the second conical block 405, thereby disassembling the first hollow shell 1 and the second hollow shell 2 and facilitating the repair of the power supply component 3.Simultaneously, the heat generated by the operation of the power supply component 3 is conducted to the surface of the heat dissipation fins 503 through the heat conduction plate 502. The heat dissipation fins 503 achieve a heat dissipation effect, thereby reducing the risk of overheating and damage to the power supply component 3 and extending its service life. This solves the problem that most existing power adapters typically use bolts or fixing methods to connect the casing, which is cumbersome to disassemble and install, and makes it inconvenient to inspect and maintain the internal power conversion components. Furthermore, the continuous operation of the power adapter generates a large amount of heat, and the inability to dissipate this heat accelerates the aging of the power conversion components, thus reducing the lifespan of the power adapter.
