Description

Technical Field

[0001] This application relates to the field of power adapter technology, and in particular to a power adapter. Background Technology

[0002] A power adapter is a power conversion device for electronic appliances. It is widely used in devices such as cordless phones, game consoles, language repeaters, portable music players, laptops, and cellular phones. A power adapter generally consists of a casing, a power transformer, and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type; according to the connection method, it can be divided into wall plug type and desktop type. Power adapters are widely used in various fields such as industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, and instrumentation.

[0003] Currently, when traditional power adapters are used outdoors, the high temperature, humidity, and unpredictable weather conditions in the outdoor environment can negatively impact their heat dissipation performance. Due to the high ambient temperature or lack of effective heat dissipation methods, the internal temperature of the adapter may rise, affecting the stability of the power adapter's operation. Summary of the Invention

[0004] To improve the stability of power adapters, this application provides a power adapter.

[0005] The power adapter provided in this application adopts the following technical solution: A power adapter includes a power adapter body. A first mounting groove is formed on one side wall of the power adapter body, and a cooling fan is installed in the first mounting groove. A second mounting groove is formed on the other side wall of the power adapter body, and a filter is installed in the second mounting groove. Both the first mounting groove and the second mounting groove are in communication with the interior of the power adapter body.

[0006] By adopting the above technical solution, when the power adapter is running, the cooling fan starts working, effectively dissipating the heat generated inside the adapter to the external environment through ventilation, preventing the internal temperature from becoming too high. On the other hand, a second mounting slot is provided on the other side wall of the power adapter body. This second mounting slot allows for air circulation, and a filter is installed inside. The filter effectively prevents external dust and debris from entering the adapter, thus keeping the cooling fan and other internal components clean and ensuring the efficient operation of the cooling system. Therefore, when used outdoors, the power adapter can more effectively cope with high-temperature and harsh environmental conditions, ensuring the normal operation of the cooling system and improving the stability and reliability of the power adapter.

[0007] Preferably, the power adapter body is provided with two sets of fixing components for fixing the cooling fan. The fixing components include a plug rod, which is slidably disposed on the power adapter body in a vertical direction. The side wall of the cooling fan is provided with a slot, and the plug rod is inserted into the slot.

[0008] By adopting the above technical solution, during the fixing process, when it is necessary to install the cooling fan onto the power adapter body, the user slides the plug vertically to the slot position, ensuring that the plug and slot are properly engaged. This engagement mechanism provides a reliable way to securely fix the cooling fan to the adapter, preventing loosening or shaking during operation. Conversely, when it is necessary to unlock and remove the cooling fan, the user can slide the plug vertically out of the slot, disengaging the plug from the slot. This simple operation allows the cooling fan to be easily disassembled for maintenance or replacement.

[0009] Preferably, the fixing component further includes a guide rod arranged in a vertical direction, the guide rod being fixed to the plug rod, and a guide groove being opened on the surface of the power adapter body, the guide rod being inserted into the guide groove.

[0010] By employing the above technical solution, the guide rod is fixed to the plug rod, while the guide groove engages with the guide rod to assist in the vertical sliding of the plug rod. During cooling fan installation, the interaction between the guide rod and the guide groove helps ensure the plug rod moves along the predetermined vertical direction. This alignment mechanism reduces errors, making it easier for the plug rod to find and insert into the corresponding slot, ensuring the correct position of the cooling fan on the power adapter body.

[0011] Preferably, a pull ring is fixed to the end of the guide rod.

[0012] By adopting the above technical solution, the pull ring allows users to perform manual operation more conveniently when inserting and sliding the guide rod. By grasping or pulling the pull ring, users can more precisely control the position of the guide rod, ensuring that the rod is accurately inserted into the guide slot, thereby achieving precise positioning of the cooling fan.

[0013] Preferably, a limiting block is fixed at the end of the guide rod, a limiting groove is formed in the groove wall of the guide groove, and the limiting block is slidably disposed in the limiting groove in the vertical direction.

[0014] By adopting the above technical solution, when the limiting block reaches the end position of the limiting groove, it restricts the further sliding of the plug rod, ensuring that the cooling fan is firmly fixed to the adapter body. This limiting mechanism effectively prevents the cooling fan from accidentally detaching or becoming unstable, improving the reliability and safety of the entire device.

[0015] Preferably, the fixing component further includes a return spring, one end of which is fixed to the guide rod, and the other end of which is fixed to the surface of the power adapter body.

[0016] By adopting the above technical solution, after the user completes the insertion or removal of the cooling fan, the return spring can quickly return the plug to its original position due to its elastic properties. This design simplifies the entire operation process, eliminating the need for the user to manually reset the plug, thus improving ease of use.

[0017] Preferably, the end of the insertion rod is provided with a guide surface, and the guide surface is arc-shaped.

[0018] By adopting the above technical solution, the arc-shaped guide surface can more accurately guide the insertion rod to find the correct position during the insertion process and ensure that the insertion rod and the guide groove are properly matched. This not only improves the insertion efficiency of the insertion rod, but also reduces the possibility of errors.

[0019] Preferably, a baffle is mounted on the surface of the power adapter body, and the baffle is inclined.

[0020] By adopting the above technical solution, the baffle serves to block rain. The inclined setting of the baffle helps to guide rainwater away from the openings and interfaces of the adapter, reducing the risk of moisture intrusion and thus protecting electronic components from the effects of a humid environment.

[0021] Preferably, a plurality of pads are fixed on the lower surface of the power adapter body.

[0022] By adopting the above technical solution, the pad can provide a certain gap between the power adapter body and the supporting surface, promote air circulation, help heat dissipation, and at the same time, the presence of the pad can also help prevent scratches or wear caused by direct friction between the power adapter body and the supporting surface, thus extending the service life of the power adapter.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When used outdoors, the power adapter can more effectively cope with high temperature and harsh environmental conditions, ensuring the normal operation of the heat dissipation system, thereby improving the stability and reliability of the power adapter; 2. The baffle serves to protect against rain. The angled design of the baffle helps to guide rainwater away from the openings and interfaces of the adapter, reducing the risk of moisture intrusion and thus protecting electronic components from the effects of a humid environment.

[0028] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0029] This application discloses a power adapter. (Refer to...) Figure 1 and Figure 2 A power adapter includes a power adapter body 1, which is arranged in a cuboid shape. An input connector 11 is installed on one side wall of the power adapter body 1, and an output connector 12 is installed on the opposite side wall of the power adapter body 1.

[0030] Furthermore, the other two side walls of the power adapter body 1 are respectively provided with a first mounting groove 13 and a second mounting groove 14. The bottom of the first mounting groove 13 and the second mounting groove 14 are provided with air holes (not shown in the figure). The size of the air holes is smaller than the size of the first mounting groove 13 and the second mounting groove 14. The air holes are connected to the interior of the power adapter body 1, thereby realizing the conduction of gas.

[0031] Specifically, a cooling fan 2 is installed in the first mounting slot 13, and a filter 3 is installed in the second mounting slot 14. The cooling fan 2 and the first mounting slot 13 are plugged into each other. Correspondingly, the power adapter body 1 is provided with a fixing component 4 for limiting the horizontal displacement of the cooling fan 2 (in conjunction with...). Figure 3 The fixing component 4 is used to fix the cooling fan 2 to the power adapter body 1. In addition, the filter 3 is fixed in the second mounting slot 14 by bolts.

[0032] In summary, when the power adapter is running, the cooling fan 2 starts working, effectively dissipating the heat generated inside the adapter to the external environment through ventilation, preventing the internal temperature from becoming too high. On the other hand, a second mounting slot 14 is provided on the other side wall of the power adapter body 1. This second mounting slot 14 allows for airflow, and a filter 3 is installed within it. The filter 3 effectively prevents external dust and debris from entering the adapter, thus keeping the cooling fan 2 and other internal components clean and ensuring the efficient operation of the cooling system. Therefore, when used outdoors, the power adapter can more effectively cope with high-temperature and harsh environmental conditions, ensuring the normal operation of the cooling system and improving the stability and reliability of the power adapter.

[0033] Furthermore, a support rod 15 is vertically fixed on the upper surface of the power adapter body 1. There are four support rods 15 arranged in a matrix. A baffle 16 is fixed on the top of the four support rods 15. The baffle 16 is inclined and tilted downward from the side of the cooling fan 2 toward the side of the filter 3.

[0034] Therefore, the baffle 16 serves to protect against rain. The tilted arrangement of the baffle 16 helps to guide rainwater away from the openings and interfaces of the adapter, reducing the risk of moisture intrusion and thus protecting electronic components from the effects of a humid environment.

[0035] Furthermore, a number of pads 17 are fixed on the lower surface of the power adapter body 1. In this embodiment, four pads 17 are provided, and the four pads 17 are arranged in a matrix on the lower surface of the power adapter body 1. The pads 17 are made of silicone with a certain degree of wear resistance.

[0036] Therefore, the pad 17 can provide a certain gap between the power adapter body 1 and the supporting surface, promote air circulation, help dissipate heat, and at the same time, the presence of the pad 17 also helps to prevent scratches or wear caused by direct friction between the power adapter body 1 and the supporting surface, thus extending the service life of the power adapter.

[0037] Reference Figure 1 and Figure 3 Specifically, there are two sets of fixing components 4, which are symmetrically arranged vertically about the power adapter body 1. Taking one set of fixing components 4 as an example, the fixing component 4 includes a connecting plate 41, a plug rod 42, a guide rod 43, and a return spring 44.

[0038] The connecting plate 41 is horizontally positioned and is rectangular in shape. It slides vertically onto the power adapter body 1. Two insertion rods 42 are provided, vertically fixed to the side wall of the connecting plate 41. Correspondingly, the side wall of the cooling fan 2 has slots 21, the number and position of which correspond to the positions of the insertion rods 42, and the insertion rods 42 are inserted into the slots 21.

[0039] Correspondingly, during the fixing process, when it is necessary to install the cooling fan 2 onto the power adapter body 1, the user controls the movement of the connecting plate 41 to allow the plug 42 to slide vertically to the position of the slot 21, ensuring that the plug 42 and the slot 21 are properly engaged. This engagement mechanism provides a reliable way to securely fix the cooling fan 2 to the adapter, preventing loosening or shaking during operation. Conversely, when it is necessary to unlock and remove the cooling fan 2, the user can slide the plug 42 vertically out of the slot 21, disengaging the plug 42 from the slot 21. This simple operation allows the cooling fan 2 to be easily disassembled for maintenance or replacement.

[0040] Furthermore, the end of the insertion rod 42 is provided with a guide surface, which is arc-shaped. The arc-shaped guide surface can more accurately guide the insertion rod 42 to find the correct position during insertion and ensure that the insertion rod 42 and the guide groove 18 are properly matched. This not only improves the insertion efficiency of the insertion rod 42, but also reduces the possibility of errors.

[0041] On the other hand, the guide rod 43 passes through the connecting plate 41 and is fixed to the connecting plate 41. The guide rod 43 is located in the middle of the connecting plate 41 and is arranged in a cuboid shape. At the same time, the surface of the power adapter body 1 has a guide groove 18, and the guide rod 43 is inserted into the guide groove 18. Correspondingly, the sliding movement of the connecting plate 41 is controlled by the guide rod 43.

[0042] Therefore, the guide rod 43 is fixed to the insertion rod 42, while the guide groove 18, through its insertion engagement with the guide rod 43, jointly assists in the vertical sliding of the insertion rod 42. During the installation of the cooling fan 2, the cooperation between the guide rod 43 and the guide groove 18 helps ensure that the insertion rod 42 moves along a predetermined vertical direction. This alignment mechanism reduces errors, making it easier for the insertion rod 42 to find and insert into the corresponding slot 21, ensuring the correct position of the cooling fan 2 on the power adapter body 1.

[0043] Furthermore, the top of the guide rod 43 rotatably supports a pull ring 431, which allows the user to more conveniently perform manual operation when inserting and sliding the guide rod 43. By grasping or pulling the pull ring 431, the user can more precisely control the position of the guide rod 43, ensuring that the insertion rod 42 is accurately inserted into the guide slot 18, thereby achieving precise positioning of the cooling fan 2.

[0044] In addition, a limiting block (not shown in the figure) is fixed at the end of the guide rod 43, and a limiting groove (not shown in the figure) is opened in the groove wall of the guide groove 18. The limiting block is slidably disposed in the limiting groove in the vertical direction.

[0045] Therefore, when the limiting block reaches the end of the limiting groove, it restricts the further sliding of the insertion rod 42, ensuring that the cooling fan 2 is firmly fixed to the adapter body. This limiting mechanism effectively prevents the cooling fan 2 from accidentally detaching or becoming unstable, improving the reliability and safety of the entire device.

[0046] On the other hand, there are two reset springs 44, which are located on both sides of the connecting plate 41. The reset springs 44 are parallel to the guide rod 43. One end of the reset spring 44 is fixed perpendicularly to the surface of the connecting plate 41, and the other end of the reset spring 44 is fixed perpendicularly to the surface of the power adapter body 1.

[0047] Therefore, after the user completes the insertion or removal of the cooling fan 2, the return spring 44 can quickly return the plug 42 to its original position due to its elastic properties. This design simplifies the entire operation process, eliminating the need for the user to manually reset the plug 42 and improving ease of use.

[0048] The implementation principle of a power adapter according to an embodiment of this application is as follows: When the power adapter is running, the cooling fan 2 starts working, effectively dissipating the heat generated inside the adapter to the external environment through ventilation, preventing the internal temperature from becoming too high. On the other hand, a second mounting slot 14 is provided on the other side wall of the power adapter body 1. This second mounting slot 14 allows for air circulation, and a filter 3 is installed within it. The filter 3 effectively prevents external dust and debris from entering the adapter, thus keeping the cooling fan 2 and other internal components clean and ensuring the efficient operation of the cooling system. Therefore, when used outdoors, the power adapter can more effectively cope with high-temperature and harsh environmental conditions, ensuring the normal operation of the cooling system and improving the stability and reliability of the power adapter.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
