Description

Technical Field

[0001] The utility model relates to the field of power management, in particular to a multi-channel power management module. Background Art

[0002] Power supply is an integral part of any electronic product. The quality of power supply directly affects the function and life of electrical equipment. With the continuous refinement and diversification of functions of electrical equipment, the requirements for power supply are getting higher and higher. The mainstream power supply methods for electrical equipment on the market today are external power supply and on-board power supply, and the output forms are generally single-channel and multi-channel fixed voltage output.

[0003] There are many types of existing multi-channel power management modules. With the development of the times, many multi-channel power management modules currently have heat dissipation functions. For example, a multi-channel power management module with publication number: CN213305246U can improve the heat dissipation efficiency of the power management module body through the setting of a radiator. The movable plate can press the fixed block through the fixed frame, the movable plate, the fixed block, the guide rod and the first spring. The movable plate and the fixed block can be connected and fixed through the fixed column, the second spring and the card block, so that the multi-channel power management module has good heat dissipation performance, improves the service life of the multi-channel power management module, and is convenient for people to use.

[0004] However, in the actual installation process of the radiator of the multi-channel power management module mentioned above, the operator needs to first place the radiator on the power management module body, then press the card block into the fixed column, and then press the movable plate, and finally release the card block to complete the installation. When removing the radiator, the card block also needs to be pressed into the fixed column, and then the restriction on the card block is gradually released as the movable plate is reset to ensure that the card block enters the groove opened on the movable plate before the card block can be released. Otherwise, the card block will pop out and it is necessary to press the card block again, which makes the radiator of the power management module very inconvenient to install and disassemble, and the operation is also cumbersome. Therefore, it is urgently needed to improve the existing power management module. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] Embodiment 1

[0033] A multi-channel power management module, such as Figure 1 - Figure 4As shown, it includes a power management module body 1 and a radiator 3, a mounting frame 2 is installed on the power management module body 1, and a mounting plate 4 slidably connected to the mounting frame 2 is installed at the end of the radiator 3, so that the radiator 3 and the mounting plate 4 can slide synchronously, so that after the position of the mounting plate 4 is restricted by the mounting frame 2, the position of the radiator 3 will also be restricted, so as to facilitate the installation of the radiator 3, so that the radiator 3 can be movably installed on the power management module body 1 through the mounting plate 4 and the mounting frame 2, because a card block 6 is slidably installed in the side wall of the end of the mounting plate 4, and because a positioning groove 9 corresponding to the card block 6 is opened on the side wall of the mounting frame 2, when the card block 6 enters the positioning groove 9, the connection between the mounting plate 4 and the mounting frame 2 will be further restricted, so that the mounting plate 4 at this time will be fixed by the mounting frame 2 and the card block 6 and the positioning groove 9, so that the radiator 3 can be smoothly installed to the power management module body 1. The locating groove 9 is provided with a spring 7 connected with the card block 6, and when the card block 6 enters the locating groove 9, the spring 7 will squeeze the card block 6, so that when the card block 6 corresponds to the position of the positioning groove 9, the spring 7 will push the card block 6 into the positioning groove 9 under the action of its own elastic force, so as to ensure that the mounting plate 4 will be automatically fixed after it moves to the limited position, and a push block 8 for pushing the card block 6 is slidably installed in the positioning groove 9, and the end of the push block 8 that does not contact the card block 6 is located outside the mounting frame 2, so that when the radiator 3 needs to be removed, the card block 6 can be moved away from the positioning groove 9 by pressing the push block 8, so that the mounting plate 4 loses the restriction given by the card block 6 and the positioning groove 9. At this time, the operator can remove the radiator 3 from the power management module body 1 by pulling it outward, so that the radiator 3 of the power management module body 1 can be disassembled and installed very conveniently.

[0034] See also Figure 2 and Figure 3 and Figure 5 Because the corners on both sides of the end of the mounting plate 4 located in the mounting frame 2 are designed with arc-shaped rounded corners, when the mounting plate 4 enters the mounting frame 2, the arc-shaped rounded corners at the end of the mounting plate 4 will guide itself, while ensuring that the mounting plate 4 can smoothly enter the mounting frame 2, while reducing the difficulty of the mounting plate 4 entering the mounting frame 2, and the top and side walls of the mounting plate 4 are both in contact with the inner wall of the mounting frame 2, so that after the mounting plate 4 enters the mounting frame 2, it will be restricted by the mounting frame 2, so that the position of the mounting plate 4 after entering the mounting frame 2 is initially fixed.

[0035] See also Figure 2 and Figure 5An outer wall of the end of the mounting plate 4 located in the mounting frame 2 is provided with an oblique groove 5. Since the depth of the oblique groove 5 is gradually reduced from the end of the mounting plate 4 located in the mounting frame 2 to the other end, the thickness of the mounting plate 4 near the mounting frame 2 is the thinnest. Therefore, when the mounting plate 4 just enters the mounting frame 2, the position where the oblique groove 5 is provided will not directly contact the mounting frame 2, thereby further reducing the difficulty of the mounting plate 4 entering the mounting frame 2.

[0036] See also Figure 2 - Figure 4 Two blocks 6 are symmetrically installed in the outer walls on both sides of the outer end of the mounting plate 4, so that there are corresponding blocks 6 and corresponding positioning grooves 9 on both sides of the mounting plate 4, further ensuring the fixity of the mounting plate 4 after installation, and the corners of the outer ends of the blocks 6 close to the inner wall of the mounting frame 2 are beveled, so that when the blocks 6 follow the mounting plate 4 into the mounting frame 2, the bevel of the blocks 6 will contact the corners of the mounting frame 2, because the end corners of the mounting frame 2 that contact the blocks 6 are also beveled, so that the bevel of the blocks 6 and the bevel of the mounting frame 2 will guide the blocks 6, ensuring that the blocks 6 It will automatically enter the mounting plate 4 during the process of the mounting plate 4 entering the mounting frame 2, thereby ensuring that the mounting plate 4 can smoothly enter the mounting frame 2, eliminating the operator's operation of manually pushing the card block 6 into the mounting plate 4. Because the corners of the opening position of the positioning groove 9 are designed with an oblique angle, the difficulty of the card block 6 entering the positioning groove 9 is reduced, ensuring that the card block 6 can smoothly enter the positioning groove 9. At the same time, when the card block 6 follows the mounting plate 4 to slide out of the mounting frame 2, the oblique angle of the positioning groove 9 will also prevent the end of the card block 6 from being stuck with the opening position of the positioning groove 9, which will affect the accident of the mounting plate 4 sliding out.

[0037] See also Figure 3 and Figure 4 Because the width of the push block 8 is greater than the width of the clamping block 6, after the push block 8 pushes the clamping block 6 into the mounting plate 4, the push block 8 cannot continue to slide in the direction of the mounting plate 4, thereby preventing the push block 8 from entering the mounting plate 4, resulting in an accident in which the mounting plate 4 cannot slide out of the mounting frame 2. A limiting groove 91 for the sliding of the push block 8 is provided in the mounting frame 2, so that the sliding of the push block 8 will be restricted by the limiting groove 91, ensuring that the push block 8 can only slide horizontally.

[0038] See also Figure 3 and Figure 4, the top and bottom of one end of the push block 8 located in the positioning groove 9 are both installed with a limit plate 10, and at the same time, the limit plate 10 will not contact the block 6, so that the limit plate 10 will not affect the sliding out of the mounting plate 4, and because the sum of the thickness of the limit plate 10 and the thickness of the push block 8 is greater than the thickness of the limit groove 91, after the push block 8 is pushed into the positioning groove 9 by the block 6, the limit plate 10 at this time will conflict with the inner wall of the positioning groove 9, making it impossible for the push block 8 to complete the passing through the limit groove 91, thereby preventing the push block 8 from sliding out of the positioning groove 9 through the limit groove 91, ensuring that the push block 8 can be used for a long time, and during the pushing Limiting plates 10 are also installed on the top and bottom of the other end of the push block 8, so that both ends of the push block 8 will be restricted by the limiting plates 10. When the limiting plates 10 conflict with the inner wall of the positioning groove 9, the distance between the limiting plates 10 at the outer end of the push block 8 and the outer wall of the mounting frame 2 is the same as the distance between the end of the push block 8 and the opening of the positioning groove 9. After the operator pushes the push block 8, the push block 8 can only slide to the opening of the positioning groove 9 under the restriction of the limiting plates 10, so that the push block 8 will not affect the sliding of the mounting plate 4, ensuring that the setting of the push block 8 will not seriously affect the installation and disassembly of the mounting plate 4.

[0039] Embodiment 2

[0040] A multi-channel power management module, such as Figure 1 - Figure 5 As shown, the technical scheme and parts of this embodiment are basically the same as those of the first embodiment, and the technically identical parts will not be repeated here. The difference is that a resistance component in contact with the mounting plate 4 is arranged in the mounting frame 2, and the resistance component is composed of a spring 2 11, a push plate 12 and a telescopic rod 13, wherein a plurality of groups of springs 11 are installed at equal intervals in the mounting frame 2, and a push plate 12 in contact with the outer wall of the end of the mounting plate 4 is installed at the end of the spring 2 11, so that when the mounting plate 4 slides into the mounting frame 2, its end will conflict with the push plate 12, and as the mounting plate 4 continues to slide, the push plate 12 will be squeezed and begin to squeeze the spring 2 11, and because a plurality of groups of telescopic rods 13 connected to the push plates 12 are installed in the mounting frame 2, the telescopic rod 13 at this time will press the spring 2 11 is used for support, and at the same time, the stability of the push plate 12 when sliding is ensured, so that after the position of the mounting plate 4 is restricted, the push plate 12 will still give the mounting plate 4 a thrust under the action of the multiple sets of springs 11, causing the end side wall of the clamping block 6 to always conflict with the inner wall of the positioning groove 9, thereby further ensuring the stability of the radiator 3 after installation, and when the mounting plate 4 loses the restriction given by the clamping block 6, the push plate 12 at this time will push the mounting plate 4 to the outside of the mounting frame 2 under the action of the spring 11, causing the mounting plate 4 to move outward for a distance after losing the restriction, thereby causing the clamping block 6 to be misaligned with the positioning groove 9, thereby causing the operator to be separated from the push block 8 at this time, and the clamping block 6 cannot enter the positioning groove 9, which makes it more convenient for the operator to disassemble the radiator 3.

[0041] The working principle of the utility model is as follows: when installing the radiator 3, first place it on the top of the power management module body 1, and then push the radiator 3 so that the mounting plate 4 starts to slide into the mounting frame 2. As the mounting plate 4 gradually enters the mounting frame 2, the inclined surface of the clamping block 6 will conflict with the oblique angle of the end of the mounting frame 2. Since the mounting plate 4 is still sliding into the mounting frame 2 at this time, the clamping block 6 is forced to start sliding into the mounting plate 4, thereby squeezing the spring 1 7. After the mounting plate 4 is installed, the clamping block 6 will correspond to the position of the positioning groove 9, causing the top of the mounting plate 4 to lose its restriction. At this time, the spring 1 7 will use its own elastic force to push the clamping block 6 into the positioning groove 9, thereby limiting the position of the mounting plate 4, and then fixing the position of the radiator 3. In the process of the mounting plate 4 sliding into the mounting frame 2, the end of the mounting plate 4 will squeeze the multiple push plates 12, thereby squeezing the spring 2 11.

[0042] When the heat sink 3 needs to be removed, first press the two push blocks 8 to push the end of the card block 6, so that the card block 6 moves out of the positioning groove 9. Because the width of the push block 8 is greater than the width of the card block 6, the push block 8 will not enter the mounting plate 4, so that the mounting plate 4 will lose its restriction at this time. At the same time, the spring 2 11 will push the heat sink 3 out of the mounting frame 2, so that the heat sink 3 will move slightly, so that the position of the card block 6 and the positioning groove 9 is staggered. At this time, the operator can pull the heat sink 3 to drive it, so that the heat sink 3 of this module is very convenient to install and remove, and is more convenient to use.

[0043] In general, when the radiator 3 needs to be removed from the power management module body 1, it is only necessary to press the push block 8 and then pull the radiator 3 outward to remove it from the power management module body 1. When the radiator 3 needs to be installed, it is only necessary to process the mounting plate 4 and push it into the mounting frame 2 to complete the installation and fixation of the radiator 3, making the disassembly and installation of the radiator 3 of the power management module body 1 very convenient and more convenient to use.

[0044] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
