[0026] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0027] In the following description, specific examples of general selection are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0028] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of a feature, whole, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, or combinations thereof.

[0029] Please see Figures 1 to 5This utility model discloses an aviation power socket with USB and TYPE-C interfaces, comprising a socket housing 1, one end of which is recessed to form two independent first mounting slots 2 and second mounting slots 3; it also includes a first transformer plate 4, which is mounted in the first mounting slot 2 and is electrically connected to a USB interface 5, which extends from the first mounting slot 2 to the outside of the socket housing 1; it also includes a second transformer plate 6, which is mounted in the second mounting slot 3 and is electrically connected to a TYPE-C interface 7, which extends from the second mounting slot 3 to the outside of the socket housing 1; and a power input connector 8, which is mounted in the socket housing 1 at the other end away from the USB interface 5 and the TYPE-C interface 7, and is electrically connected to both the first transformer plate 4 and the second transformer plate 6. In this device, power is supplied through the power input connector 8, passing through the first transformer board 4 and the second transformer board 6. The transformer boards rectify and filter the input current, then adjust the voltage to the required level through a converter before outputting through the interface. The second transformer board 6, electrically connected to the TYPE-C interface 7, is designed with multiple DC-DC conversion stages, enabling buck, boost, or bidirectional conversion. Its internal microcontroller or dedicated chip communicates with the device according to the USB PD protocol, automatically adjusting output parameters to meet the device's maximum accepting capacity. Therefore, the TYPE-C interface 7 enables fast charging of mobile devices. In this embodiment, 28V DC power is input through the power input connector 8. After a protection mechanism, one set of power is input to the first transformer board 4 for voltage adjustment before outputting 5V and 2.1A through the USB interface 5. The other set is input to the second transformer board 6. The TYPE-C chip automatically identifies the power of the receiving device and automatically adjusts the voltage and current (5V 3A, 9V 3A, 12V 3A, 20V 3A) before outputting through the TYPE-C interface 7.

[0030] Please see Figure 2 and Figure 4 To prevent dust from entering through the first mounting slot 2 and the second mounting slot 3 and affecting the electrical performance of the first transformer plate 4 and the second transformer plate 6, this invention also includes a socket cover plate 9. The socket cover plate 9 is adapted to the socket housing 1 to cover the first mounting slot 2 and the second mounting slot 3. The surface of the socket cover plate 9 is also designed with two through holes 10 corresponding to the positions of the USB interface 5 and the TYPE-C interface 7. By covering the first mounting slot 2 and the second mounting slot 3 of the socket housing 1 with the socket cover plate 9, a sealed cavity is formed to prevent dust from entering, while exposing the output interface. This satisfies the charging needs and isolates the internal components of the socket housing 1 from the outside, ensuring the stable operation of its electrical components.

[0031] Please see Figure 2 To facilitate the maintenance and replacement of the first transformer plate 4 and the second transformer plate 6 within the first mounting slot 2 and the second mounting slot 3, in this invention, the socket cover plate 9 has a fixing protrusion 18 on the side facing the socket housing 1, which is adapted to connect with the socket housing 1. By installing fasteners into the fixing protrusion 18, the socket cover plate 9 and the socket housing 1 form a detachable connection. Connecting the socket housing 1 and the socket cover plate 9 with fasteners not only securely fixes the socket cover plate 9 to the socket housing 1, but also allows for easy disassembly of the socket cover plate 9 and the socket housing 1.

[0032] Please see Figure 2 , Figures 5 to 8 In order to fix the socket to an external object, the socket housing 1 is designed with fixing grooves 12 on both sides, and the fixing grooves 12 are respectively provided with corresponding first through holes 19 and second through holes 20; it also includes a threaded vertical rod 14, which is installed in the fixing grooves 12 on both sides through the first through holes 19 and the second through holes 20; it also includes a pressure plate 13, which is sleeved on the threaded vertical rod 14; it also includes a spring 15 and a fixing knob 16, with the spring 15 sleeved on the threaded vertical rod 14 and the fixing knob 16 installed in the second through hole 20, one end of the spring 15 abutting against the pressure plate 13 and the other end abutting against the fixing knob 16.

[0033] More specifically, the pressure plate 13 is designed with an L-shaped structure, including an abutment part and an installation part. The installation part is threaded and fits onto the threaded vertical rod 14. This threaded design allows the rotational motion of the threaded vertical rod 14 to be converted into the linear motion of the pressure plate 13 along the threaded vertical rod 14. The abutment part is used to abut against a plate-shaped external object, forming a fixed connection between the socket and the external object. Simultaneously, to facilitate the rotation of the threaded vertical rod 14, the socket cover 9 is also provided with two threaded vertical rod through holes 11. By using a tool to pass through the threaded vertical rod through holes 11 and rotating the threaded vertical rod 14, the power socket can be detached from the external object. Furthermore, the threaded vertical rod 14 is not installed in the middle of the fixing groove 12, but rather on either side of the fixing groove 12. This design is based on the different movement states of the pressure plate 13 during the installation and disassembly of the socket housing 1.

[0034] When it is necessary to fix the socket to an external object, use a tool to rotate the threaded vertical rod 14, causing the pressure plate 13 to unscrew from the fixing groove 12. As the threaded vertical rod 14 continues to rotate, the pressure plate 13 moves vertically towards the socket cover plate 9 along the thread direction of the threaded vertical rod 14 until the abutting end of the pressure plate 13 contacts the external object. Then, continue to adjust the threaded vertical rod 14 until the socket is fixed to the external object, thus completing the installation. When it is necessary to remove the socket from the external object, rotate the threaded vertical rod 14 in the opposite direction to the above rotation. Rotating the threaded vertical rod 14 causes the pressure plate 13 to move away from the external object along with the rotation of the threaded vertical rod 14. At this time, the pressure plate 13 gradually moves away from the socket cover plate 9 along the thread direction of the threaded vertical rod 14, finally completing the removal. In practical applications, this structure can be used to fix the socket to the armrest or side of an aircraft seat.

[0035] Please see Figure 2 and Figure 5 To ensure a proper connection between the power input connector 8 and the power source, in this invention, a connecting block 17, integrated with the socket housing 1, is provided at the end of the socket housing 1 furthest from the socket cover 9. The power input connector 8 is connected to the socket housing 1 by embedding the connecting block 17. During aviation operations, due to the specific nature of its application, the power input connector 8 requires a certain external adaptation structure when connected to the power source. Therefore, the connecting block 17 is designed to connect the power input connector 8, thereby adapting it to the aviation field.

[0036] The advantages of this utility model are:

[0037] 1. This utility model is equipped with both a USB interface and a TYPE-C interface to meet passengers' charging needs for devices with different interfaces.

[0038] 2. This utility model also includes a fixing groove, a threaded vertical rod, a pressure plate, a spring, and a fixing knob. By rotating the threaded vertical rod, the degree of engagement of the socket with external objects can be controlled, which facilitates the installation and disassembly of the socket and makes maintenance easier.

[0039] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
