Description

Technical Field

[0001] This utility model relates to the field of adapter technology, specifically to a dual-mode power adapter that can switch between wired and wireless power supply. Background Technology

[0002] An adapter is a device used to connect two different devices or systems, enabling them to work together. In the field of electronics, it is often used in power supply scenarios, such as converting high-voltage AC mains power to the low-voltage required by electronic devices to ensure their safe and stable operation. Furthermore, adapters can solve interface incompatibility problems, such as converting a USB interface to an HDMI interface, thereby enabling data transfer or signal conversion between different devices, greatly expanding the range of applications and compatibility of devices.

[0003] In existing technology, the plug of a dual-mode power adapter with switchable wired and wireless power supply is rotated using a rotating shaft structure. The plug is mounted on a rotating shaft, which is fixed to the adapter body. This allows the plug to rotate around the rotating shaft. Simultaneously, a positioning device, such as a flexible positioning protrusion and a corresponding positioning groove, can be provided at the connection between the rotating shaft and the adapter body. When the plug rotates to a specific angle, the positioning protrusion engages with the positioning groove, stabilizing the plug at that angle and meeting different usage requirements.

[0004] The rotating shaft structure is relatively simple, but its stability is limited. During frequent rotation, the plug may wobble, affecting the tightness of the connection with the socket, which may lead to problems such as poor contact and unstable power supply, making it impossible to rotate the plug efficiently. To address these issues, a dual-mode power adapter with switchable wired and wireless power supply is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0034] Reference Figure 1 and Figure 4 This utility model discloses a dual-mode power adapter with switchable wired and wireless power supply, including an adapter body 1, an electromagnetic coil 28 fixedly connected to the bottom of a limiting plate 27, and the top of the electromagnetic coil 28 threadedly connected to a lead screw 26. The electromagnetic coil 28 can provide wireless charging for the adapter body 1. LED lights 2 are fixedly connected to the top of the adapter body 1, which can facilitate the observation of the charging status of the adapter body 1. A data cable 3 is fixedly connected to the rear end of the adapter body 1. A slider 10 is fixedly connected through and attached to one side of the outer ring of the rotating rod 11. The slider 10 drives one side of the rotating rod 11 to slide.

[0035] Reference Figure 2 and Figure 3A housing 4 is fixedly connected to one front end of the adapter body 1. A first worm gear 5 is rotatably connected through the front end of the housing 4. A rotating shaft 7 is rotatably connected through the front end of one side of the housing 4. A first worm wheel 6 is fixedly connected to one end of the rotating shaft 7. Through the meshing of the worm wheel and the worm, the first worm 5 drives the first worm wheel 6 to rotate synchronously. The first worm wheel 6 and the first worm 5 are meshed together. A spring 8 is fixedly connected to the inner wall of the rotating shaft 7. A limit rod 9 is fixedly connected to one end of the spring 8. The rotation of the rotating shaft 7 causes the limit rod 9 to rotate accordingly. The release of the spring 8 allows the limit rod 9 to move. A second worm gear 14 is rotatably connected through the other side of the adapter body 1. A first threaded rod 16 is rotatably connected through the other side of the inner wall of the adapter body 1. A threaded block 13 is threadedly connected through the outer ring of the first threaded rod 16. The movement of the first threaded rod 16 causes the threaded block 13 to move back and forth. One end of the first threaded rod 16 is fixedly connected to the second worm gear 15, which drives the first threaded rod 16 to rotate. The second worm gear 15 is meshed with the second worm 14. The front end of the inner wall of the adapter body 1 is slidably connected to the plug 17. The front end of the plug 17 is fixedly connected to the rotating rod 11, and the other end of the rotating rod 11 is slidably connected to the limit rod 9. The rotation of the rotating rod 11 can drive the plug 17 to rotate. One end of the rotating rod 11 is fixedly connected to the limit ring 12, which is rotatably connected to one side of the threaded block 13. The rotation of the limit ring 12 will not drive the threaded block 13 to rotate synchronously. The middle of the rear end of one side of the adapter body 1 is connected to the second knob 22. A protective component is provided on one side of the adapter body 1.

[0036] Reference Figure 4 and Figure 5 The protective assembly includes a first knob 18, which is rotatably connected to the bottom of the rear end of one side of the adapter body 1. One end of the first knob 18 is fixedly connected to a bidirectional threaded rod 19, allowing easy rotation of the bidirectional threaded rod 19. Each bidirectional threaded rod 19 has a nut pair 20 threadedly connected to its outer ring. A sealing baffle 21 is fixedly connected to the front end of the nut pair 20. Movement of the nut pair 20 causes the sealing baffle 21 to move accordingly, and the connection between the sealing baffles 21 is sealed. One end of the second knob 22 is fixedly connected to… There is a bevel gear set 23, and a third worm gear 24 is fixedly connected to the front end of the bevel gear set 23. One bevel gear in the bevel gear set 23 is connected to the third worm gear 24, and the other is connected to the second knob 22. A lead screw 26 is rotatably connected through the middle of the inner wall of the adapter body 1. The outer ring of the lead screw 26 is threadedly connected to a limit plate 27. The rotation of the lead screw 26 causes the limit plate 27 to move up and down, and the sealing baffle 21 can be inserted into the limit plate 27. A third worm wheel 25 is fixedly connected to the top of the lead screw 26, and the third worm wheel 25 is meshed with the third worm gear 24.

[0037] Working principle: First, when the plug 17 needs to be removed, the second worm gear 14 is rotated, causing the second worm wheel 15 to drive the first threaded rod 16 to rotate. The rotation of the first threaded rod 16 causes the threaded block 13 to move, which in turn causes the internal limiting ring 12 to move. This causes the plug 17 to slide out via the rotating rod 11. As the slider 10 moves along with it, the limiting rod 9 and the spring 8 are compressed. When the slider 10 reaches its limit position, the spring 8 is released, allowing the limiting rod 9 to insert into the rotating rod 11. When the plug 17 needs to be rotated, the first worm gear 5 is rotated, causing the first worm wheel 6 to drive the limiting rod 9 and the rotating rod 11 to rotate. Because the adapter body 1 has a groove on the top, it is convenient to rotate the plug. The plug 17 can be rotated 90° by rotating the first knob 18, allowing the angle of the plug 17 to be adjusted according to different needs. The plug 17 can also be retracted when not in use. When wireless charging is needed, the first knob 18 is turned to rotate the bidirectional threaded rod 19, which drives the sealing baffle 21 to slide out through the nut pair 20. The second knob 22 is turned again, which drives the third worm gear 24 to rotate through the bevel gear set 23. This causes the third worm wheel 25 to drive the lead screw 26 to rotate synchronously, which allows the limiting plate 27 to drive the electromagnetic coil 28 to slide down. Finally, the first knob 18 is turned to insert the sealing baffle 21 into the limiting plate 27, thus providing efficient protection for the electromagnetic coil 28 and preventing dust from entering when wireless charging is not in use.
