Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter with high-efficiency heat dissipation. Background Art

[0002] With the rapid development of modern technology, electronic devices have become an indispensable part of people's lives and work. As a crucial accessory for electronic devices, power adapters convert mains electricity to a specific voltage and current suitable for electronic devices, ensuring their proper operation. However, as the performance of electronic devices continues to improve, their power consumption also increases, placing higher demands on the heat dissipation capabilities of power adapters.

[0003] Traditional power adapters have the following main problems in heat dissipation:

[0004] 1. The power components inside the power adapter generate a significant amount of heat during operation. Due to its relatively enclosed structure, heat is difficult to dissipate and tends to accumulate internally. Prolonged heat accumulation can cause the internal temperature of the power adapter to rise, which not only affects the electrical performance of the power components and reduces their efficiency, but can also accelerate the aging of electronic components and shorten the lifespan of the power adapter. For example, in some electronic devices that operate continuously for long periods of time, such as servers and game consoles, the power adapters they support often overheat due to poor heat dissipation, resulting in decreased performance and even system failures.

[0005] Second, the most common heat dissipation method for power adapters is natural heat dissipation, which utilizes the heat dissipation area of ​​the casing to dissipate heat into the surrounding environment. This method has low heat dissipation efficiency and often cannot meet the heat dissipation requirements of high-power power adapters. Although some power adapters also use auxiliary heat dissipation measures such as heat sinks, in some high-temperature environments or high-load operating conditions, it is still difficult to effectively dissipate heat in a timely manner, thus affecting the stability and reliability of the power adapter.

[0006] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0008] A power adapter with high heat dissipation efficiency includes an upper cover, a lower cover, and a power assembly, wherein the upper cover and the lower cover are butted against each other to form a receiving cavity for the power assembly;

[0009] A window connected to the accommodating cavity is provided along the end surface of the upper cover. The upper cover is provided with a drawer in its window. A cover plate is slidably connected to the drawer. The cover plate is used to open or close the window. A dustproof net is provided in the window, and the dustproof net is gap-matched with the cover plate.

[0010] As a further solution of the present invention: the upper cover includes a first plate and a second plate joined by ultrasonic welding, the first plate is provided with a protruding plug on the mating surface thereof with the second plate, and the second plate is provided with a concave slot on the mating surface thereof with the first plate, and the plug is engaged with the slot;

[0011] The drawer includes a first slide groove opened on the first plate and a second slide groove opened on the second plate, and the first slide groove and the second slide groove are connected to each other, and the cover plate can be slidably engaged between the first slide groove and the second slide groove, wherein the window is located in the first plate and corresponds to the first slide groove.

[0012] As a further solution of the present invention: a stop block is protruded from the outer side of the cover plate, and a groove adapted for the stop block is formed on the inner side of the first plate located at the window, and the stop block is elastically engaged with the groove.

[0013] As a further solution of the present invention: the cover plate includes a first sliding portion and a second sliding portion convexly arranged along the end surface of the first sliding portion, and the second sliding portion is located within the vertical projection range of the first sliding portion;

[0014] Wherein, both sides of the first sliding portion are respectively extended outward to form a slide rail, and the first slide groove / the second slide groove is provided with a guide groove adapted to the slide rail.

[0015] As a further solution of the present invention: the first plate is provided with a step protruding from the inner side of the window thereof for supporting the front end of the cover plate.

[0016] As a further solution of the present invention: a protrusion is provided along the end surface of the cover plate to form a dialing portion.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1) By opening a window in the upper cover, the heat dissipation area is increased, which is conducive to faster heat dissipation to the external environment. Compared with the traditional method of relying solely on natural heat dissipation of the shell, the heat dissipation efficiency is significantly improved. The window design is directly connected to the accommodating cavity where the power component is located, so that the heat generated by the power component can be dissipated more directly, reducing the possibility of heat accumulation inside, thereby effectively reducing the temperature inside the power adapter, improving the electrical performance and working efficiency of the power component, and extending the service life of the power adapter;

[0019] 2) The dustproof net installed in the window can prevent dust from entering the accommodating cavity during the heat dissipation process, preventing dust from adhering to and contaminating the power components and circuit boards. This not only keeps the inside of the power adapter clean, but also prevents the degradation of heat dissipation performance and the occurrence of faults such as short circuits caused by dust accumulation, thereby improving the reliability and safety of the power adapter.

[0020] 3) The cover is slidably connected to the drawer, and users can easily open or close the window according to actual usage. When quick heat dissipation is needed, the cover can be easily opened; when heat dissipation is not required or dust prevention is required, the cover can be closed. This design improves the convenience and flexibility of users in using the power adapter and meets the usage needs in different scenarios. At the same time, the clearance fit design also ensures the smooth operation of the cover, and will not affect the user experience due to interference with the dustproof net.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-5 In an embodiment of the present invention, a power adapter with high efficiency in heat dissipation includes an upper cover 1, a lower cover 2, and a power component. The upper cover 1 and the lower cover 2 are butted against each other to form a receiving cavity for the power component.

[0032] A window 3 connected to the accommodating cavity is provided along the end surface of the upper cover 1. The upper cover 1 is provided with a drawer in its window 3. A cover plate 4 is slidably connected to the drawer. The cover plate 4 is used to open or close the window 3. A dustproof net 5 is provided in the window 3, and the dustproof net 5 is gap-fitted with the cover plate 4.

[0033] In the technical solution of the present utility model, the upper cover 1 and the lower cover 2 are docked with each other to form an accommodating cavity for placing the power supply component (not shown), providing a relatively closed installation space for the power supply component, protecting the power supply component from external physical damage, and laying a basic structure for subsequent heat dissipation and dustproof design; a window 3 is opened on the end face of the upper cover 1 at the connection point of the accommodating cavity, the purpose of which is to increase the heat dissipation channel so that the heat generated by the power supply component during operation can be more effectively dissipated to the external environment through the window 3, and a drawer is arranged in the window 3. On the one hand, the drawer can serve as an installation carrier for the dustproof net 5, and on the other hand, the drawer can be easily pulled out from the window 3, which is convenient for maintenance operations such as cleaning or replacing the dustproof net 5; the cover plate 4 slidably connected to the drawer is used to control the opening and closing of the window 3. When heat dissipation is required, the cover 4 can be opened to allow heat to dissipate through the window 3; when the power adapter is not in use or a large amount of dust needs to be prevented from entering, the cover 4 can be closed to play a certain role in dust prevention and protection of the internal structure; the dustproof net 5 is arranged in the window 3 and has a clearance fit with the cover 4. Its main function is to prevent external dust from entering the accommodating cavity when the window 3 is opened for heat dissipation, protect the power supply components from dust pollution, thereby ensuring the normal operation and heat dissipation performance of the power adapter, and the clearance fit can ensure that the cover 4 will not interfere with the dustproof net 5 in the process of sliding to open or close the window 3, while also ensuring the effective coverage area of ​​the dustproof net 5, thereby improving the dustproof effect;

[0034] By providing the window 3 in the upper cover 1, the heat dissipation area is increased, which facilitates faster heat dissipation to the external environment. Compared with the traditional method of relying solely on natural heat dissipation of the outer shell, the heat dissipation efficiency is significantly improved. The design of the window 3 is directly connected to the accommodating cavity where the power supply component is located, so that the heat generated by the power supply component can be dissipated more directly, reducing the possibility of heat accumulation inside, thereby effectively reducing the temperature inside the power adapter, improving the electrical performance and working efficiency of the power supply component, and extending the service life of the power adapter. For example, when the power adapter is used in an electronic device that works continuously for a long time, the stability of the device can be better maintained, reducing the occurrence of performance degradation or freezes due to overheating.

[0035] The dustproof net 5 provided in the window 3 can prevent dust from entering the accommodating cavity during the heat dissipation process, thereby preventing dust from adhering to and contaminating the power supply components and circuit boards. This not only keeps the interior of the power adapter clean, but also prevents the occurrence of heat dissipation performance degradation and short circuit faults caused by dust accumulation, thereby improving the reliability and safety of the power adapter.

[0036] The cover plate 4 is slidably connected to the drawer, and the user can conveniently open or close the window 3 according to actual usage. When rapid heat dissipation is required, the cover plate 4 can be easily opened; when heat dissipation is not required or dust prevention is required, the cover plate 4 can be closed. This design improves the convenience and flexibility of the user in using the power adapter and meets the usage requirements in different scenarios. At the same time, the clearance fit design also ensures the smooth operation of the cover plate 4, and will not affect the user experience due to interference with the dustproof net 5.

[0037] Among them, a circle of inwardly recessed grooves can be designed on the edge of the internal window 3 of the drawer, and the edge of the dustproof net 5 can be embedded in this groove to achieve fixation. The design of the drawer and the cover 4 facilitates the cleaning and replacement of the dustproof net 5. When a certain amount of dust accumulates on the dustproof net 5, the dustproof net 5 can be cleaned or replaced with a new one by pulling out the drawer, thereby ensuring the long-term effective use of the dustproof net 5, thereby continuously maintaining the dustproof effect of the power adapter.

[0038] In the embodiment of the present utility model, the upper cover 1 includes a first plate 6 and a second plate 7 that are joined by ultrasonic welding. The first plate 6 is provided with a protruding plug 8 on the mating surface thereof with the second plate 7. The second plate 7 is provided with a recessed slot 9 on the mating surface thereof with the first plate 6. The plug 8 is plugged into the slot 9.

[0039] The drawer includes a first slide groove 10 opened on the first panel 6 and a second slide groove 11 opened on the second panel 7, and the first slide groove 10 and the second slide groove 11 are connected to each other, and the cover plate 4 can be slidably engaged between the first slide groove 10 and the second slide groove 11, wherein the window 3 is located in the first panel 6 and corresponds to the first slide groove 10.

[0040] The upper cover 1 is divided into the first plate 6 and the second plate 7 to facilitate the installation of the cover plate 4. By arranging a structure corresponding to the window 3 and a partial drawer structure (first slide groove 10) on the first plate 6, and arranging another partial drawer structure (second slide groove 11) on the second plate 7, operations can be performed separately during the assembly process. For the installation of the cover plate 4, this split design allows one side of the cover plate 4 to be embedded in the first slide groove 10 first, and then when the first plate 6 and the second plate 7 are combined, the other side of the cover plate 4 can smoothly enter the second slide groove 11, thereby realizing the sliding connection of the cover plate 4 between the two slide grooves. Compared with the design of the integral upper cover 1, this installation method is more flexible and convenient. There is no need to complete the precise installation of the cover plate 4 and the slide groove in a narrow space at one time, which reduces the installation difficulty and the requirements for the assembly process.

[0041] The plug-in column 8 on the first plate 6 is plugged into the slot 9 on the second plate 7, which not only enhances the structural stability of the upper cover 1 as a whole, but also plays an important role in the installation process of the cover plate 4. When the upper cover 1 is assembled, the cooperation between the plug-in column 8 and the slot 9 can be used as a positioning reference to ensure that the first plate 6 and the second plate 7 can be accurately spliced ​​together. Such a positioning function is crucial to ensuring the connectivity and alignment accuracy of the first slide groove 10 and the second slide groove 11. Only when the two slide grooves are accurately aligned can the cover plate 4 slide smoothly between them to realize the function of opening and closing the window 3. Therefore, the design of the plug-in column 8 and the slot 9 indirectly ensures the normal performance of the cover plate 4 after installation, making the entire structure more reasonable and reliable.

[0042] Ultrasonic welding is adopted in combination with the connection method of the plug post 8 and the slot 9, which greatly improves the connection strength and stability of the upper cover 1. Compared with traditional connection methods (such as screw connection, etc.), ultrasonic welding does not require the use of additional connectors, reduces the number of parts and assembly processes, and also avoids the problem of reduced sealing performance of the upper cover 1 due to loose or damaged connectors. This stable and sealed upper cover 1 structure can effectively prevent external dust, moisture and other impurities from entering the interior of the power adapter, protect the power components from erosion, and improve the reliability and service life of the power adapter.

[0043] In the embodiment of the present invention, a stop block 12 is protruded from the outer side of the cover plate 4 , and a groove 13 adapted for the stop block 12 is opened on the inner side of the first plate 6 located at the window 3 , and the stop block 12 is elastically engaged with the groove 13 .

[0044] When the cover plate 4 slides to the position of closing the window 3, the stopper 12 enters the position of the groove 13 as the cover plate 4 moves. The stopper 12 and the groove 13 adopt an elastic snap-fitting mode, which means that the stopper 12 will be subject to a certain elastic resistance when entering the groove 13. When the stopper 12 completely enters the groove 13, due to the elastic restoring force, the stopper 12 will be tightly snapped together with the groove 13. This elastic snap-fitting is usually achieved by providing an elastic material (such as a rubber pad or a plastic structure with elastic deformation ability) at the stopper 12 or the groove 13, or by utilizing the elastic deformation ability of the material of the cover plate 4 itself to complete the snap-fitting;

[0045] This design is a further optimization based on the overall structure of the upper cover 1, drawer and cover plate 4 of the power adapter. When the cover plate 4 slides between the first slide groove 10 and the second slide groove 11, the stop block 12 moves with the cover plate 4. When the window 3 is closed, the snap fit between the stop block 12 and the groove 13 is a locking mechanism for the position of the cover plate 4. It works together with other structures of the drawer and the upper cover 1 to ensure that the cover plate 4 can stably cover the window 3 to achieve the functions of dustproof and protection of the internal structure. At the same time, this snap fit method also needs to be coordinated with the sliding operation of the cover plate 4 to achieve reliable locking when closed without affecting the normal sliding of the cover plate 4 to open and close the window 3.

[0046] In the embodiment of the present utility model, the cover plate 4 includes a first sliding portion 14 and a second sliding portion 15 convexly provided along the end surface of the first sliding portion 14 , and the second sliding portion 15 is located within the vertical projection range of the first sliding portion 14 ;

[0047] Both sides of the first sliding portion 14 are extended outward to form a slide rail 16 , and the first slide groove 10 / the second slide groove 11 is provided with a guide groove 17 adapted to the slide rail 16 .

[0048] The first and second slide grooves 11 are provided with guide grooves 17 adapted to the slide rails 16 , so that the cover plate 4 can slide smoothly on the drawer. When the cover plate 4 is installed on the drawer, the slide rails 16 will be embedded in the guide grooves 17 , and the guide grooves 17 provide a precise movement track for the slide rails 16 ; the slide rails 16 on both sides of the first slide portion 14 cooperate with the guide grooves 17 on the first and second slide grooves 11 to increase the contact area and connection points between the cover plate 4 and the drawer. Compared with the simple plane sliding connection method, this design with the slide rails 16 and the guide grooves 17 can better withstand the friction and tension generated by the cover plate 4 during the sliding process, thereby enhancing the connection strength and reliability between the two, which makes it less likely for the cover plate 4 to become loose, fall off or deform during long-term use, thereby extending the service life of the power adapter.

[0049] In the embodiment of the present invention, a step 18 for supporting the front end of the cover plate 4 is protruded from the inner side of the window 3 of the first plate 6 .

[0050] A step 18 is provided on the inner side of the window 3 of the first plate 6. This step 18 is a raised structure with a certain height and width. Its position is specially selected on the inner side of the window 3, corresponding to the movement trajectory and closed position of the cover plate 4. When the cover plate 4 slides to the state of closing the window 3, the front end of the cover plate 4 (usually refers to the end close to the first plate 6) will fall exactly on this step 18. The height and width design of the step 18 need to match the size and shape of the cover plate 4 to ensure that the cover plate 4 can be placed stably on the step 18 and form a tight fit with the step 18 in the closed state without shaking or excessive gap. When the cover plate 4 slides on the drawer, as the cover plate 4 gradually approaches the closed position of the window 3, the step 18 will first contact the front end of the cover plate 4, guiding the cover plate 4 to accurately enter the closed position. At the same time, the step 18 works together with the slide structure of the drawer to limit the movement of the cover plate 4 in the vertical direction, so that the cover plate 4 can stably cover the window 3, achieving functions such as sealing and dustproof.

[0051] In the embodiment of the present invention, a protrusion is provided along the end surface of the cover plate 4 to form a dialing portion 19 for the user to operate the cover plate 4 .

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
