Description
Technical Field
[0001] This application relates to the field of charger technology, and in particular to a multi-interface PD fast charger. Background Technology
[0002] PD fast chargers are a fast charging technology protocol based on the USB Type-C interface. They achieve higher power and more efficient charging by intelligently adjusting voltage and current, and are widely used in devices such as mobile phones, laptops, and tablets.
[0003] A Chinese patent, titled "A Dustproof PD Fast Charger with a Plug," patent number CN221041676U, publication date May 28, 2024, describes a charging mechanism with a dustproof mechanism fixedly installed at one end. The dustproof mechanism includes a mounting shell, a first magnet, a fixing cover, and a second magnet. The mounting shell is fixedly installed at one end of the charging mechanism. A USB port is located inside one end of the PD fast charger. During use, the data cable is inserted into the USB port, but it is mostly unused. After prolonged disuse, dust accumulates inside the USB port, causing internal damage or blockage, rendering it unusable. The mounting shell is fixedly installed at one end of the PD fast charger, and the first magnet is located inside the mounting shell. A fixing cover is used to prevent dust from entering, and a second magnet is located on the fixing cover. The first and second magnets attract each other, securing the fixing cover and preventing it from falling off, thus achieving a dustproof effect.
[0004] Although the design can protect the USB port from dust, the plug is exposed when not in use and is not protected against dust. Therefore, the dust protection effect of this design is not high. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a multi-interface PD fast charger that solves the problem that the plug is exposed to the outside when not in use and is not dustproof, resulting in poor dustproof performance.
[0006] The above-mentioned objective of this application is achieved through the following technical solution: a multi-interface PD fast charger, including a charger body, a receiving slot is provided on one side of the charger body, a two-prong plug is provided in the receiving slot, the two-prong plug is electrically connected to the charger body, a rotating component is provided on the charger body for the two-prong plug to rotate in the receiving slot, and a dustproof component is provided on the charger body for dust protection of the two-prong plug and the charger body.
[0007] Furthermore, two rotating holes are respectively provided on the two inner walls opposite to each other in the receiving groove. Two rotating components are provided and are respectively located at the rotating holes. The rotating components include rotating shafts, connecting blocks, springs and plug-in pins. One end of each of the two rotating shafts is fixedly connected to both sides of the two-prong plug, and the other end of each of the two rotating shafts is rotatably connected to the rotating holes. The connecting block is fixedly installed on the rotating shaft. A placement groove is provided on the side of the connecting block away from the two-prong plug. The spring is fixedly connected to the bottom of the placement groove. The end of the spring away from the placement groove is fixedly connected to the plug-in pin. The end of the plug-in pin away from the spring is set as an arc surface. Arc-shaped sliding grooves and two snap-fit grooves are respectively provided on the two opposite sides of the receiving groove. The two ends of the arc-shaped sliding grooves are respectively connected to the two snap-fit grooves, and the plug-in pins are snapped into the snap-fit grooves.
[0008] Furthermore, the charger body has strip-shaped grooves on opposite sides. The dustproof component includes two sliders and a protective cover. The protective cover has an opening on the side closest to the charger body. The two sliders are fixedly installed on opposite sides inside the protective cover. The charger body and the two-prong plug are located inside the protective cover. The sliders are slidably connected to the strip-shaped grooves.
[0009] Furthermore, V-shaped spring pieces are fixedly installed on opposite sides of the slider, with one side of the V-shaped spring piece fitting against the inner wall of the strip groove.
[0010] Furthermore, a first limiting frame is fixedly installed at the opening of the protective cover, and a second limiting frame is fixedly installed on the side of the charger body away from the two-prong plug.
[0011] Furthermore, a first magnet is fixedly installed on the side of the first limiting frame away from the protective cover, and a second magnet is fixedly installed on the side of the second limiting frame close to the first limiting frame. The magnetic poles of the first magnet and the second magnet are opposite on the sides that are close to each other.
[0012] Furthermore, several connection ports are provided on the side of the charger body away from the two-prong plug.
[0013] In summary, this application includes at least one of the following beneficial technical effects: During use, the two-prong plug can be rotated out of the receiving slot by rotating the component, with the angle adjustable from 0 to 90°; after use, the plug can be rotated back into the receiving slot, and the plug and charger body are sealed and protected by the dustproof component to prevent dust accumulation and extend the service life of the plug.
[0014] In use, rotating the two-pronged plug causes the rotating shafts on both sides to rotate within the rotating holes, simultaneously rotating the connecting block. At this time, the arc-shaped end of the plug is pressed against the inner wall of the locking groove, compressing the spring and causing the plug to slide along the arc-shaped groove. The arc-shaped groove is designed with a 90° arc, with each end connected to one of the two locking grooves. When the plug rotates to the 90° position, the plug automatically engages with the corresponding locking groove under the spring's rebound force, achieving stable positioning. This allows the device to quickly unfold or retract the plug, improving ease of use, while ensuring the plug remains stable at different angles, preventing loosening.
[0015] During installation of the protective cover, the slider is pushed in along the strip groove, and the inclined surface of the V-shaped spring contacts the inner wall of the groove, generating elastic deformation. Due to the elastic characteristics of the V-shaped structure, the V-shaped spring continuously applies pressure to the inner wall of the groove, forming stable frictional resistance, ensuring that the protective cover is tightly fixed to the charger body and preventing accidental loosening. The elastic pressure of the V-shaped spring makes the assembly process more stable and reliable, while also facilitating subsequent disassembly and maintenance. Attached Figure Description

[0018] The present application will be further described in detail below with reference to the accompanying drawings.
[0019] Example, refer to Figures 1-5A multi-interface PD fast charger includes a charger body 1. A receiving slot 11 is provided on one side of the charger body 1, and a two-prong plug 12 is disposed within the receiving slot 11. The two-prong plug 12 is electrically connected to the charger body 1. A rotating component 2 is provided on the charger body 1 for rotating the two-prong plug 12 within the receiving slot 11. A dustproof component 3 is provided on the charger body 1 for dust protection of the two-prong plug 12 and the charger body 1. During use, the two-prong plug 12 can be rotated out of the receiving slot 11 by rotating the rotating component 2, with an adjustable angle range of 0-90°. After use, the plug can be rotated back into the receiving slot 11, and the dustproof component 3 seals and protects the plug and charger body 1, preventing dust accumulation and extending the plug's lifespan.
[0020] The receiving groove 11 has two rotating holes 111 on its two opposite inner walls. Two rotating components 2 are provided and are located at the rotating holes 111 respectively. The rotating components 2 include a rotating shaft 21, a connecting block 22, a spring 23 and a plug 24. One end of the two rotating shafts 21 is fixedly connected to both sides of the two-prong plug 12, and the other end of the two rotating shafts 21 is rotatably connected to the rotating holes 111 respectively. The connecting block 22 is fixedly installed on the rotating shaft 21. A placement groove 221 is provided on the side of the connecting block 22 away from the two-prong plug 12. The spring 23 is fixedly connected to the bottom of the placement groove 221. The end of the spring 23 away from the placement groove 221 is fixedly connected to the plug 24. The end of the plug 24 away from the spring 23 is set as an arc surface. The receiving groove 11 has an arc-shaped sliding groove 112 and two snap-fit grooves 113 on its opposite sides. The two ends of the arc-shaped sliding groove 112 are connected to the two snap-fit grooves 113 respectively. The plug 24 is snapped into the snap-fit groove 113. In use, rotating the double-pronged plug 12 causes the rotating shafts 21 on both sides to rotate within the rotating holes 111, while the connecting block 22 rotates accordingly. At this time, the arc-shaped end of the plug 24 is pressed against the inner wall of the locking groove 113, compressing the spring 23, and causing the plug 24 to slide along the arc-shaped slide groove 112. The arc-shaped slide groove 112 is designed with a 90° arc, and both ends are connected to the two locking grooves 113. When the plug rotates to the 90° position, the plug 24 automatically engages with the corresponding locking groove 113 under the restoring force of the spring 23, achieving stable positioning. This allows the device to quickly unfold or retract the plug, improving ease of use, while ensuring the plug remains stable at different angles and preventing loosening.
[0021] The charger body 1 has strip-shaped grooves 13 on opposite sides. The dustproof component 3 includes two sliders 31 and a protective cover 32. The protective cover 32 has an opening on the side closest to the charger body 1. The two sliders 31 are fixedly installed on opposite sides inside the protective cover 32. The charger body 1 and the two-prong plug 12 are located inside the protective cover 32, and the sliders 31 are slidably connected within the strip-shaped grooves 13. When storing the charger, first rotate the two-prong plug 12 back into the receiving slot 11. Then, align the open end of the protective cover 32 with the charger body 1, aligning the sliders 31 on both sides with the strip-shaped grooves 13, and push the protective cover 32 along the direction of the strip-shaped grooves 13 until it completely covers the charger body 1 and the plug. The protective cover 32, through its sliding closing design, can tightly wrap the charger, effectively preventing dust and foreign objects from entering, while also preventing the plug from being damaged due to exposure, thus extending its service life.
[0022] V-shaped spring pieces 311 are fixedly installed on opposite sides of the slider 31, with one side of each V-shaped spring piece 311 fitting against the inner wall of the strip groove 13. When installing the protective cover 32, the slider 31 is pushed into the strip groove 13, and the inclined surface of the V-shaped spring piece 311 contacts the inner wall of the strip groove 13, generating elastic deformation. Due to the elastic characteristics of the V-shaped structure, the V-shaped spring piece 311 continuously applies pressure to the inner wall of the strip groove 13, forming stable frictional resistance and ensuring that the protective cover 32 is tightly fixed to the charger body 1, preventing accidental loosening. The elastic pressure of the V-shaped spring piece 311 makes the assembly process more stable and reliable, while also facilitating subsequent disassembly and maintenance.
[0023] A first limiting frame 33 is fixedly installed at the opening of the protective cover 32, and a second limiting frame 34 is fixedly installed on the side of the charger body 1 away from the two-prong plug 12. When the protective cover 32 is slidably installed into place, the first limiting frame 33 and the second limiting frame 34 engage with each other to form a limit, controlling the installation position of the protective cover 32, ensuring that the protective cover 32 completely covers the charger body 1, and preventing the protective cover 32 from sliding excessively or becoming misaligned, thereby enhancing the overall structural stability and making the dust protection more rigorous and reliable.
[0024] A first magnet 331 is fixedly installed on the side of the first limiting frame 33 away from the protective cover 32, and a second magnet 341 is fixedly installed on the side of the second limiting frame 34 close to the first limiting frame 33. The magnetic poles of the first magnet 331 and the second magnet 341 are opposite on the sides that are close to each other. When the protective cover 32 slides to the installation position, the first limiting frame 33 and the second limiting frame 34 are attracted by magnetic attraction. The opposite magnetic poles of the first magnet 331 and the second magnet 341 generate a strong attraction force, making the protective cover 32 fit tightly against the charger body 1, ensuring a dustproof and sealing effect.
[0025] The charger body 1 has several wiring ports 14 on the side away from the two-prong plug 12. When using the device, the wiring ports 14, the charger body 1, and the two-prong plug 12 are electrically connected, and the provision of several wiring ports 14 improves the convenience of the device.
[0026] Working principle: When storing the charger body 1, rotate the two-prong plug 12 back into the receiving slot 11. Rotating the two-prong plug 12 causes the rotating shafts 21 on both sides to rotate within the rotating holes 111. At the same time, the connecting block 22 rotates accordingly. At this time, the arc-shaped end of the plug 24 is squeezed by the inner wall of the locking groove 113, causing the spring 23 to compress. The plug 24 slides along the arc-shaped slide groove 112 until the plug 24 is engaged in another locking groove 113, completing the storage of the two-prong plug 12. Then, align the opening end of the protective cover 32 with the charger body 1, so that the sliders 31 on both sides engage with the strip-shaped slide groove 13. Align and push the protective cover 32 along the direction of the strip groove 13. The inclined surface of the V-shaped spring piece 311 contacts the inner wall of the strip groove 13 and produces elastic deformation until it completely covers the charger body 1 and the plug. At this time, the first magnet 331 and the second magnet 341 attract each other. The strong attraction force of the opposite magnetic poles of the first magnet 331 and the second magnet 341, as well as the continuous pressure of the V-shaped spring piece 311 on the inner wall of the strip groove, form a stable frictional resistance, so that the protective cover 32 fits tightly with the charger body 1, protects the charger body 1 and the two-prong plug 12, and prevents dust.
[0027] The embodiments described in this specific implementation are 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.
