[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] This utility model embodiment provides a power adapter, such as Figures 1 to 2 As shown, the power adapter includes a housing 1, a first circuit board 7, a charging interface 2, a display screen 6, a first side panel 4, and a touch switch 5. The housing 1 includes a first side panel 121 and a second side panel 122 adjacent to the first side panel 121. The first side panel 121 has a first mounting groove 1211, and the second side panel 122 has a second mounting groove 1221 communicating with the first mounting groove 1211. The first circuit board 7 is installed inside the housing 1. The charging interface 2 is located at the first mounting groove 1211, and the display screen 6 and the touch switch 5 are located at the second mounting groove 1221. The first side panel 4 includes a first sub-board 41 and a second sub-board 42 connected to the first sub-board 41. The first sub-board 41 is installed in the first mounting groove 1211, and the second sub-board 42 is installed in the second mounting groove 1221. The charging interface 2 is exposed through the first mounting groove 1211 and the first sub-board 41. The second sub-board 42 covers the display screen 6 and the touch switch 5, and at least the area of ​​the second sub-board 42 corresponding to the display screen 6 is a light-transmitting area.

[0020] The power adapter of this utility model features a first side plate 4, which includes a first sub-plate 41 and a second sub-plate 42. When the first sub-plate 41 and the second sub-plate 42 are installed in the first mounting slot 1211 and the second mounting slot 1221, the second sub-plate 42 covers the display screen 6 and the touch switch 5. At least the area of ​​the second sub-plate 42 corresponding to the display screen 6 is a light-transmitting area, ensuring the normal display of the display screen 6. This prevents the display screen 6 and the touch switch 5 from being exposed to the housing 1, avoiding dust accumulation and damage. The charging interface 2 is located in the first mounting slot 1211, and the display screen 6 and the touch switch 5 are located in the second mounting slot 1221. This separates the charging interface 2 from the display screen 6 and the touch switch 5 on different surfaces, the first side plate 121 and the second side plate 122. Users can plug in the charging cable at the first side plate 121 and control the touch switch and observe the information displayed on the display screen 6 at the second side plate 122. This convenient operation fully utilizes the different surface areas of the housing 1, providing a good user experience.

[0021] Furthermore, by having the first sub-plate 41 and the second sub-plate 42 of the first side plate 4 simultaneously cover the first mounting slot 1211 and the second mounting slot 1221, the design of the power adapter is enhanced, resulting in a more aesthetically pleasing and unique appearance. The arrangement of the first mounting slot 1211 and the second mounting slot 1221 ensures the secure installation of the first sub-plate 41 and the second sub-plate 42, while also making the overall appearance of the power adapter more attractive.

[0022] like Figure 3 As shown, positioning posts 43 are provided on the inner sides of the first sub-plate 41 and the second sub-plate 42. Positioning holes 123 are provided in the first mounting groove 1211 and the second mounting groove 1221 corresponding to the positioning posts 43. The positioning posts 43 are inserted into the positioning holes 123 for positioning. The precise positioning of the positioning posts 43 ensures the accuracy of the position of the first sub-plate 41 and the second sub-plate 42 when installed in the first mounting groove 1211 and the second mounting groove 1221. Furthermore, the cooperation between the positioning posts 43 and the positioning holes 123 makes the installation process simpler and faster. During assembly, the first sub-plate 41 and the second sub-plate 42 can be quickly and accurately installed into the predetermined positions, reducing installation time and improving production efficiency. After the positioning posts 43 are inserted into the positioning holes 123, they provide fixation and support for the first sub-plate 41 and the second sub-plate 42, and, in cooperation with the first mounting groove 1211 and the second mounting groove 1221, enhance the installation stability of the first side plate 4.

[0023] More specifically, each edge of the first sub-board 41 and the second sub-board 42 is provided with a hook 44, and the first mounting groove 1211 and the second mounting groove 1221 are provided with corresponding holes 125 for the hooks 44. The hooks 44 are respectively engaged in the holes 125 to further fix the first sub-board 41 and the second sub-board 42. The first mounting groove 1211 and the first sub-board 41 are both provided with openings corresponding to the charging interface 2, and the charging interface 2 is exposed through the openings. The charging interface 2 includes four Type-C ports and one USB-A port.

[0024] Specifically, the second mounting slot 1221 has a first opening 12211, and the inner side of the second sub-board 42 has a first groove 421. A sensing sheet is attached to the first groove 421. The touch switch 5 is a touch-type capacitive switch, which extends from the first opening 12211 and abuts against the sensing sheet. By opening the first groove 421 and attaching the sensing sheet to the inner side of the second sub-board 42, the touch-type capacitive switch can tightly abut against the sensing sheet after extending from the first opening 12211. The sensing sheet increases the sensing area of ​​the touch-type capacitive switch, making the contact between the touch-type capacitive switch and the sensing sheet more direct and tight, thus improving the transmission efficiency and sensitivity of the touch signal. The touch switch 5 uses a touch-type capacitive switch, which, compared to a traditional mechanical switch, can be hidden under the second sub-board 42, ensuring a flatter outer surface of the power adapter and a simpler, more aesthetically pleasing appearance. The sensing sheet is made of copper foil, which increases the sensing area of ​​the touch-type capacitive switch.

[0025] Specifically, the first sub-board 41 and the second sub-board 42 of the first side panel 4 are integrally molded from transparent PC (polycarbonate) material. The display screen 6 can be an LCD display screen 6, an LED display screen 6, or an OLED display screen 6, etc., used to display real-time charging voltage, current, or preset animated emoticons. Its specific control and implementation can employ conventional techniques in the art, and will not be elaborated here. A touch-sensitive capacitive switch is used to control the opening of the display screen 6 and the switching of display pages. When a human touches the sensing area, the touch-sensitive capacitive switch changes the capacitance value of that area. The touch-sensitive capacitive switch senses the change in capacitance value through its built-in detection circuit, and after signal processing and judgment, triggers the corresponding switching action to realize the circuit's conduction, cutoff, or control, etc. Its specific control and implementation can employ conventional techniques in the art, and will not be elaborated here.

[0026] Furthermore, such as Figures 4 to 6As shown, the power adapter also includes a first circuit board 7 and a second circuit board 8. The charging interface 2 is electrically connected and mounted on the second circuit board 8, which is plugged into and electrically connected to the first circuit board 7. This circuit layout, where the charging interface 2 is electrically connected to the second circuit board 8 and then plugged into the first circuit board 7, makes the internal circuitry of the power adapter clearer and more organized. The circuitry related to the charging interface 2 is concentrated on the second circuit board 8, facilitating circuit design, debugging, and maintenance. It also avoids mutual interference between the charging interface 2 circuitry and other circuits, improving circuit stability and reliability. Furthermore, if the charging interface 2 or its related circuitry malfunctions, only the second circuit board 8 needs to be replaced, without disassembling the entire power adapter circuitry, significantly reducing maintenance costs and time. Moreover, the plug-in connection between the second circuit board 8 and the first circuit board 7 makes replacement simpler and faster, improving product maintainability. Additionally, the independent design of the second circuit board 8 allows for easier upgrades or expansions of the charging interface 2's functionality. For example, the second circuit board 8 can be replaced as needed to support higher power charging or different charging protocols without requiring a major overhaul of the entire power adapter, enhancing the product's adaptability and competitiveness.

[0027] Specifically, the second circuit board 8 is vertically inserted into the first circuit board 7.

[0028] Furthermore, the power adapter also includes a third circuit board 9. The display screen 6 and touch switch 5 are mounted on and electrically connected to the third circuit board 9. The third circuit board 9 is plugged into and electrically connected to the first circuit board 7. Mounting the display screen 6 and touch switch 5 on and electrically connecting them to the third circuit board 9 achieves an integrated design of the display screen 6 and touch switch 5, reducing the risk of circuit failure and improving the overall integration and reliability of the circuit. The third circuit board 9, as an independent module, is electrically connected to the first circuit board 7, facilitating modular production, assembly, and testing during the manufacturing process. The third circuit board 9 can be produced and debugged separately to ensure its performance and quality before integration with the first circuit board 7, improving production efficiency and product quality stability. During repair or replacement, only the third circuit board 9 needs to be replaced, reducing repair costs and complexity.

[0029] Specifically, the third circuit board 9 is vertically inserted into the first circuit board 7.

[0030] The second mounting slot 1221 has a first opening 12212. The display screen 6 is mounted on the inner wall of the second side panel 122 and mates with the first opening 12212. The first opening 12212 in the second mounting slot 1221, with the display screen 6 mounted on the inner wall of the second side panel 122 and mates with the first opening 12212, allows for a tight fit with the light-transmitting area on the second sub-board 42, ensuring effective light transmission and clarity of the displayed content. Specifically, the power adapter also includes a mounting bracket 30, in which the display screen 6 is mounted. The mounting bracket 30 is connected to the second circuit board 8 via a connector 4011.

[0031] Further integration Figure 7 and Figure 8 As shown, the power adapter also includes a fourth circuit board 10 and a plug 20. The fourth circuit board 10 is plugged into and electrically connected to the first circuit board 7, and the plug 20 is mounted on the housing 1 and electrically connected to the fourth circuit board 10. By adding the fourth circuit board 10 and the plug 20 and electrically connecting them to the first circuit board 7, and by mounting the plug 20 on the housing 1 and electrically connecting it to the first circuit board 7, a complete power adapter circuit system is formed. The fourth circuit board 10 can integrate power input, conversion, and other circuit functions, working in conjunction with the first circuit board 7 and other circuit boards to achieve a complete power conversion process from AC input to DC output, meeting the charging needs of electronic devices. The introduction of the fourth circuit board 10 provides more room for expanding the circuit functions of the power adapter. Additional functional circuits, such as overcurrent protection, overvoltage protection, and short-circuit protection, can be added to the fourth circuit board 10 to improve the safety performance and reliability of the power adapter. Specific configurations can be made according to needs. Specifically, the fourth circuit board 10 is vertically plugged into the first circuit board 7.

[0032] Specifically, the housing 1 includes a main housing 12 and a front housing 13, with the front housing 13 mounted on one side of the main housing 12. A first mounting groove 1211 and a second mounting groove 1221 are formed on the side of the main housing 12. The inner surface of the main housing 12 opposite to the front housing 13 is the bottom surface 124 of the main housing 12, and the portion between the bottom surface 124 and the front housing 13 is the side surface of the main housing 12.

[0033] Combination Figures 9 to 16As shown, the power adapter also includes a rotating mounting bracket 40 and two electrical connecting pieces 50. The rotating mounting bracket 40 includes a first pressure plate 401 and a second pressure plate 402. The first pressure plate 401 has a rotating groove. The plug 20 includes two oppositely arranged pins 201 and a rotating mounting shaft 202, with each end connected to one end of the two pins 201. The rotating mounting shaft 202 is installed in the rotating groove. The second pressure plate 402 is pressed onto the side of the first pressure plate 401 away from the pins 201. The first pressure plate 401 and the second pressure plate 402 are then fixedly installed on the inner wall of the main housing 12, with the first pressure plate 401 pressing against the inner wall of the main housing 12, thereby allowing the rotating mounting shaft 202 to be rotatably limited in the rotating groove. The two electrical connecting pieces 50 are pressed between the first pressure plate 401 and the second pressure plate 402, and each electrical connecting piece 50 is connected to one of the two pins 201. The two electrical connecting pieces 50 are also electrically connected to the third circuit board 9. Figure 15 As shown, two prongs 201 extend from the side of the main housing 12 and can be rotatably stored in the storage groove 126 on the side. The rotating mounting bracket 40 simplifies the rotating mounting structure of the plug 20 and makes installation convenient. Specifically, the electrical connection piece 50 is a copper sheet.

[0034] A limiting rib 127 is provided on the inner sidewall of the main shell 12, and a first limiting groove 1271 is provided on the limiting rib 127 to accommodate the rotating mounting shaft 202. The rotating mounting shaft 202 is rotatably limited in the first limiting groove 1271. The first limiting groove 1271 and the rotating groove together limit the rotating mounting shaft 202, ensuring stable installation and reliable rotation during rotation.

[0035] Specifically, the first pressure plate 401 and the second pressure plate 402 are installed together by screws. The rotating mounting bracket 40 and the plug 20 are located on one side of the main housing 12 near the corner. The second pressure plate 402 has a second limiting groove 4021 on the side away from the rotating mounting shaft 202. A limiting protrusion 128 is provided on the inner wall of the main housing 12 adjacent to the rotating mounting bracket 40. The limiting protrusion 128 is engaged in the second limiting groove 4021 on the side of the main housing 12 near the corner. On the side of the rotating mounting bracket 40 near the rotating mounting shaft 202, the first pressure plate 401 and the second pressure plate 402 are installed on the studs 129 inside the main housing 12 by screws. The second pressure plate 402 has a limiting protrusion 4022 protruding on the side near the face shell 13, and a limiting rib 131 is provided on the inner surface of the face shell 13. The limiting rib 131 surrounds a limiting groove 1311, and the limiting protrusion 4022 is inserted into the limiting groove 1311. Thus, the rotating mounting bracket 40 is securely installed in the housing 1.

[0036] Furthermore, a supporting rib 1220 is provided on the bottom surface 124 of the main shell 12, and the first pressure plate 401 is supported on the supporting rib 1220, further improving the installation stability of the rotating mounting bracket 40.

[0037] The first circuit board 7 lies flat against and is supported on the bottom surface 124 of the main housing 12. One side of the second circuit board 8 and the third circuit board 9 are supported on the inner wall of the front cover 13, while the other side is inserted into the first circuit board 7 from the side facing the front cover 13. The housing 1 adopts a split design of the main housing 12 and the front cover 13. The front cover 13 is installed on one side of the main housing 12, forming an overall housing structure for the power adapter, facilitating the production and assembly of the housing 1. The first circuit board 7 lies flat against and is supported on the bottom surface 124 of the main housing 12, providing more internal space within the main housing 12 for easier overall circuit layout. Simultaneously, one side of the second circuit board 8 and the third circuit board 9 are supported on the inner wall of the front cover 13, while the other side is inserted into the first circuit board 7 from the side facing the front cover 13. Through the cooperation of the bottom surface 124 of the main housing 12, the first circuit, the second circuit board 8, the third circuit, and the front cover 13, the installation of the first circuit, the second circuit board 8, and the third circuit is achieved, resulting in a simple structure. The face shell 13 can be installed on the main shell 12 by ultrasonic welding.

[0038] One side of the second circuit board 8 is inserted into one side of the third circuit board 9. This insertion creates a tighter connection between the two, improving their installation stability. Connecting the second circuit board 8 and the third circuit board 9 via an insertion method enhances their installation stability.

[0039] Furthermore, one side of the fourth circuit board 10 is supported on the inner wall of the casing 13, and the other side is inserted into the first circuit board 7 from the side of the first circuit board 7 facing the casing 13.

[0040] The fourth circuit board 10 is supported on one side of the inner wall of the housing 13, and the other side is inserted into the first circuit board 7 from the side of the first circuit board 7 facing the housing 13. This support method makes the fourth circuit board 10 have a stable fixing effect inside the housing 1, and can withstand a certain amount of gravity and external force, avoiding electrical connection failures caused by shaking or tilting of the circuit board during use.

[0041] The first circuit board 7 is supported on the bottom surface 124 of the main shell 12. The second circuit board 8, the third circuit board 9 and the fourth circuit board 10 are respectively supported on the side of the first circuit board 7 away from the bottom surface 124 by plugging in. Finally, they are pressed together by the shell 13, thereby realizing the overall installation and fixation of the first circuit board 7, the second circuit board 8, the third circuit board 9 and the fourth circuit board 10. The structure is simple and the installation is firm and stable.

[0042] Specifically, the four edges of the bottom surface 124 of the main shell 12 are provided with first support ribs 1241, which are connected to the inner wall of the main shell 12. The first circuit board 7 is supported on the first support ribs 1241 to improve installation stability. The inner wall of the main shell 12 is provided with guide ribs 1210 that connect to the first support ribs 1241 and extend toward the face shell 13. The end surface of the guide rib 1210 away from the first support ribs 1241 is provided with an inclined surface 12101 that gradually rises toward the first support ribs 1241.
