DETAILED DESCRIPTION

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0027] The present utility model embodiment provides a power adapter 1000, referring to Figure 1-4 As shown, the power adapter 1000 includes: a shell 100, a DC module 200, an AC plug module 300 and an adapter module 400. A first partition 101 is provided in the shell 100 to separate a first cavity 102 and a second cavity 103 in the shell 100. A second partition 104 is provided in the first cavity 102 to separate the first cavity 102 into a first chamber 105 and a second chamber 106. The DC module 200 is located in the second cavity 103, the adapter module 400 is located in the first chamber 105, the AC plug module 300 is provided in the second chamber 106, and the DC module 200 and the AC plug module 300 are electrically connected to the adapter module 400 respectively.

[0028] A first partition 101 is provided in the housing 100, and the first partition 101 separates the housing 100 into a first cavity 102 and a second cavity 103 that are independent of each other, so that the electronic components in the first cavity 102 and the second cavity 103 remain independent and do not interfere with or affect each other. A second partition 104 is provided in the first cavity 102, and the first cavity 102 is separated into a first chamber 105 and a second chamber 106 that are independent of each other, thereby separating the entire housing 100 into three independent spaces for accommodating electronic components, which can effectively isolate electronic components with different functions, ensure their physical and electromagnetic separation, avoid mutual interference and circuit interference between electronic components, improve the safety and stability of the power adapter 1000, and reduce the impact on the heat dissipation efficiency and charging efficiency of the power adapter 1000.

[0029] Specifically, the DC module 200 is located in the second cavity 103 and is electrically connected to the adapter module 400. This layout makes the DC module 200 relatively independent of other modules, facilitates its circuit design and heat dissipation, and reduces electromagnetic interference with the AC plug module 300. The adapter module 400 is arranged in the first cavity 105, and the AC plug module 300 is arranged in the second cavity 106. Separating the AC plug module 300 from other modules can reduce electromagnetic interference between it and the DC module 200, and facilitate connection with other electronic devices.

[0030] In this embodiment, the DC module 200 is a DC module with an I / O port adapter board, which is a functional module in the power adapter 1000. The DC module is mainly responsible for converting AC power into DC power to supply the DC current required by the charging device. It usually includes circuits such as rectification, filtering, and voltage stabilization, which are used to convert the input AC power into stable DC power and provide it to the charging device for charging or power supply. It can achieve functions such as voltage stabilization and current control to ensure safety and stability during the charging process.

[0031] In this embodiment, the AC plug module 300 refers to a functional module in the power adapter 1000, which is provided with a power socket 302 and a power cord 305 and related circuit connections for connecting the power adapter 1000 to a power socket. The power cord 305 usually has a power plug, which usually has a metal contact point for contacting the jack of the power socket to obtain the AC power of the power source. The power socket 302 provides a jack that matches the plug for receiving an external power plug. The AC plug module 300 can obtain the required AC power through the power cord 305 and the power socket, provide appropriate current supply for the charging device, and then transmit the current to the external power-consuming electronic device through the power socket 302 or the DC module 200.

[0032] refer to Figure 4 The power adapter 1000 further includes a first heat dissipation layer 500 and a first insulating layer 600 . The first insulating layer 600 is disposed in the housing 100 and surrounds the adapter module 400 . The first heat dissipation layer 500 is attached to the outer side of the first insulating layer 600 .

[0033] The first insulating layer 600 is disposed in the housing 100 and surrounds the adapter module 400. It provides electrical insulation protection, isolates the adapter module 400 from the housing 100, and reduces the possibility of circuit interference and mutual interference between the adapter module 400 and other electronic components in the housing 100. This insulating layer can prevent safety issues such as current leakage and short circuit, and protect the safety of users and equipment. The first heat dissipation layer 500 surrounds the outside of the first insulating layer 600, and it can effectively dissipate the heat generated by the power adapter 1000. When the power adapter 1000 generates heat during operation, the first heat dissipation layer 500 can dissipate the heat of the coated adapter module 400, transfer the heat to the surrounding environment, and prevent overheating from causing equipment failure or damage.

[0034] refer to Figure 5 and Figure 6 The adapter module 400 includes a connecting plate 403, a first circuit board 401 and a second circuit board 402. The first circuit board 401 and the second circuit board 402 are connected via the connecting plate 403. The first circuit board 401 and the second circuit board 402 are arranged relative to each other so that the electronic components on the first circuit board 401 and the second circuit board 402 maintain a certain gap.

[0035] Electronic components are respectively arranged on the first circuit board 401 and the second circuit board 402, and the first circuit board 401 and the second circuit board 402 are connected by the connecting plate 403 to form a stable whole. The first circuit board 401 and the second circuit board 402 are arranged opposite to each other, so that the electronic components on the two are arranged relative to each other, which can save space in the first chamber 105 and make the adapter module 400 occupy less space. A certain gap is maintained between the electronic components on the first circuit board 401 and the second circuit board 402, so that there is enough space for air circulation to dissipate the heat of the electronic components on the first circuit board 401 and the second circuit board 402, thereby improving the heat dissipation capacity of the adapter module 400 and preventing equipment failure or damage caused by overheating.

[0036] Specifically, the connecting plate 403 acts as a bridge connecting the first circuit board 401 and the second circuit board 402, so that they can be effectively connected and assembled together. With the existence of the connecting plate 403, the first circuit board 401 and the second circuit board 402 can be conveniently connected and fixed to form an integral structure of the adapter module 400. In this embodiment, the adapter module 400 includes two connecting plates 403, which are respectively arranged at the top and bottom of the adapter module 400, which can further enhance the structural strength of the adapter module 400.

[0037] Specifically, the first circuit board 401 and the second circuit board 402 are arranged relative to each other and maintain a certain gap. Such a design helps to isolate the electronic components on the first circuit board 401 and the second circuit board 402, and reduce the circuit interference and interference between each other. By maintaining a certain gap, crosstalk and electromagnetic interference between circuits can be reduced, and the circuit performance and stability of the adapter module 400 can be improved.

[0038] Further, refer to Figure 5 The adapter module 400 also includes a second heat dissipation layer 700 and a second insulating layer 800. The second insulating layer 800 covers the electronic components on the first circuit board 401 and the second circuit board 402 respectively. The second heat dissipation layer 700 is attached to the outside of the second insulating layer 800. A certain gap is maintained between adjacent second insulating layers 800 that respectively cover the first circuit board 401 and the second circuit board 402.

[0039] The electronic components of the first circuit board 401 and the second circuit board 402 are coated with a second insulating layer 800 and a second heat dissipation layer 700 attached to the second insulating layer 800, which can further strengthen the isolation between the first circuit board 401 and the second circuit board 402, and the isolation between the adapter module 400 and the outside world, so that the first circuit board 401 and the second circuit board 402 are relatively independent, and the electronic components of each other will not affect and interfere with each other, and the heat dissipation of the adapter module 400 is further strengthened, so that the electronic components on the first circuit board 401 and the second circuit board 402 are kept working in an appropriate temperature environment to avoid failure and damage due to high temperature.

[0040] Specifically, the second heat dissipation layer 700 is attached to the outside of the second insulating layer 800, and it can effectively dissipate the heat generated by the adapter module 400. When the adapter module 400 is working, the electronic components on the first circuit board 401 and the second circuit board 402 will generate heat, and the second heat dissipation layer 700 can provide a heat dissipation channel to transfer the heat to the surrounding environment to prevent overheating from causing equipment failure or damage.

[0041] Specifically, the second insulating layer 800 is respectively disposed on the electronic components on the first circuit board 401 and the second circuit board 402, and provides electrical insulation protection. Through the provision of the second insulating layer 800, the electronic components on the first circuit board 401 and the second circuit board 402 can be effectively isolated, and the interference and mutual interference between the circuits can be reduced. The second insulating layer 800 can prevent safety problems such as current leakage and short circuit between the first circuit board 401 and the second circuit board 402, and provide additional electrical protection.

[0042] It should be noted that a certain gap is maintained between the first circuit board 401 and the second circuit board 402, so after the second insulating layer 800 and the second heat dissipation layer 700 cover the first circuit board 401 and the second circuit board 402, a certain gap is still maintained between adjacent second heat dissipation layers 700. This gap design is conducive to air circulation and heat dissipation. Air can flow in the gap to promote heat dissipation, thereby keeping the temperature of the adapter module 400 within a reasonable range and improving the heat dissipation effect.

[0043] Further, refer to Figures 4 to 6 The second circuit board 402 extends to the second chamber 106 , the AC plug module 300 is disposed on the second circuit board 402 , and the AC plug module 300 is electrically connected to the second circuit board 402 .

[0044] The second circuit board 402 extends to the second chamber 106, so that the AC plug module 300 can be mounted on the second circuit board 402. At the same time, the AC plug module 300 is electrically connected to the second circuit board 402, so that current is transmitted from the outside to the AC plug module 300, and then the current is transmitted to the circuit of the adapter module 400 through the electrical connection between the second circuit board 402 and the AC plug module 300. Reliable circuit connection ensures stable transmission of current and normal operation of the adapter.

[0045] By extending the second circuit board 402 to the second chamber 106 and arranging the AC plug module 300 on the second circuit board 402, the space inside the adapter module 400 can be better utilized, and the overall size of the module can be reduced, making the structural design of the power adapter 1000 more compact, improving the portability of the power adapter 1000, and making it easier to carry and store.

[0046] Specifically, the design of the second circuit board 402 extending to the second chamber 106 can enhance the structural stability of the adapter module 400. As a supporting and fixing part, the second circuit board 402 can provide additional support and stability for the AC plug module 300, and prevent the AC plug module 300 from moving and vibrating in the housing 100. This helps to reduce the possibility of damage to the power adapter 1000 and improve the durability of the adapter module 400.

[0047] refer to Figure 2 , Figure 3 and Figure 5 A through hole 1051 is provided on the first chamber 105 , and the adapter module 400 further includes a connection connector 404 provided on the first circuit board 401 , and the connection connector 404 passes through the through hole 1051 and is connected to the DC module 200 .

[0048] The connection connector 404 passes through the via hole 1051 to achieve a reliable connection between the first circuit board 401 and the DC module 200. The connection connector 404 provides a stable interface to ensure a good electrical connection between the DC module 200 and the first circuit board 401. Such a connection design can reduce circuit interruption or failure caused by poor contact or looseness, and improve the reliability of the adapter module 400.

[0049] Specifically, by setting a via 1051 on the first chamber 105, the connecting joint 404 can pass through the via 1051 so that the first circuit board 401 can be quickly and conveniently connected to the DC module 200, thereby saving the internal space of the adapter module 400, improving the space utilization within the adapter module 400, and making the adapter module 400 more compact and efficient.

[0050] Further, refer to Figures 4 to 6The DC module 200 includes a third circuit board 201 , which is electrically connected to the first circuit board 401 via a connecting connector 404 . The DC module 200 is provided with at least one plug-in terminal 202 .

[0051] The third circuit board 201 is electrically connected to the first circuit board 401 through the connection connector 404. The DC module 200 is electrically connected to the adapter module 400 through the connection connector 404, ensuring that current is supplied from the adapter module 400 to the DC module 200 to power external electronic devices. The connection connector 404 provides a stable interface that can effectively transmit current and signals to ensure the normal operation of the adapter module 400.

[0052] Specifically, the DC module 200 includes an I / O port adapter board disposed on the third circuit board 201, and at least one plug terminal 202 is disposed on the I / O port adapter board, which improves the flexibility and scalability of the power adapter 1000. The plug terminal 202 can be used to connect external devices or accessories, such as a charging cable or other power supply device. Such a design enables the adapter module 400 to have a wider range of applications and can adapt to different types of devices and needs.

[0053] In this embodiment, the plug-in terminal 202 can be configured as a variety of different types, such as: USB-Type-C, USB-Type-A and micro-USB interface.

[0054] refer to Figures 2 to 6 The AC plug module 300 includes a connecting frame 301 connected to the second circuit board 402, and a power socket 302 arranged opposite to the connecting frame 301. The power socket 302 is located on opposite sides of the shell 100, and the shell 100 is provided with a first plug hole 107 corresponding to the power socket 302.

[0055] By connecting the connecting frame 301 with the second circuit board 402, the AC module is mounted on the second circuit board 402, and the power socket 302 can be connected to the circuit of the adapter module 400, so that the external current can be transmitted to the circuit of the adapter module 400 through the AC plug module 300. Reliable power connection ensures the normal operation and stable current supply of the power adapter 1000.

[0056] Specifically, the power socket 302 is located on opposite sides of the AC plug module 300 near the housing 100, and the housing 100 is provided with a first plug hole 107 corresponding to the power socket 302. This layout makes it more convenient to connect or disconnect the power socket 302 and the external power plug. The user can easily insert or unplug the external power plug into the first plug hole 107 to power the electronic device.

[0057] Further, refer to Figure 7 The AC plug module 300 includes a first connecting wire group 303 and a second connecting wire group 304.

One end of the second connecting wire group 304 is connected to the first connecting wire group 303 through the second circuit board 402, and the other end constitutes a power cord 305.

[0058] The first connecting wire group 303 connects the second circuit board 402 and the power socket 302, and transmits the current from the adapter module 400 to the power socket 302 through the second circuit board 402, and then transmits the current to external electrical appliances and electronic devices through the power socket 302. One end of the second connecting wire group 304 is connected to the first connecting wire group 303 through the second circuit board 402, and the other end forms a power line 305. The power line 305 transmits the external current to the second connecting wire group 304, and the second connecting wire group 304 transmits the current to the second circuit board 402 and the first connecting wire group 303, and then the first connecting wire group 303 transmits the current to other electronic components in the power adapter 1000.

[0059] Further, refer to Figures 2 to 4 The housing 100 further includes a front cover 108 and a rear cover 109 .

This plug hole can be used to insert other devices or connectors so that electrical appliances or electronic devices can be connected to the power adapter 1000, providing more application scenarios and flexibility.

[0061] Specifically, a through hole 1091 is provided on the back cover 109, so that the power cord 305 can pass through the through hole 1091 and extend from the inside of the housing 100 of the power adapter 1000 to the outside.
