Abstract
Description
Technical Field
[0001] This invention belongs to the field of power adapter technology, and particularly relates to a PD power adapter with wire harness storage function. Background Technology
[0002] With the widespread use of portable electronic devices such as smartphones, laptops, and tablets, users' demand for faster charging speeds is increasing. PD power adapters, with their support for variable voltage and variable current fast charging, have become one of the mainstream charging devices and are widely used in personal consumer electronics, mobile office, and other scenarios.
[0003] Existing PD power adapters typically only include the adapter body and a matching cable harness, lacking a dedicated cable harness storage structure. Users often manually and haphazardly wind the cables, leading to crossovers, overlaps, and compression. Over time, the cable harness insulation layer is prone to wear due to friction or compression, potentially causing internal copper core breakage and significantly shortening the cable harness's lifespan. When idle, the power input or data charging ports of existing PD power adapters are directly exposed to the external environment, easily accumulating dust and oil, or oxidizing the metal contacts in humid conditions.
[0004] When storing, the wire harness connectors of existing PD power adapters are usually kept perpendicular to the adapter body. During the winding process, the connectors are easily bent excessively, causing fatigue damage to the connection between the cable and the interface at the connector. On the other hand, the vertical connectors will increase the overall winding radius of the wire harness, occupy more storage space, which is not conducive to the compact storage of the adapter and reduces the portability of the device.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0035] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.
[0036] like Figures 1 to 7 As shown, in one embodiment, a PD power adapter with wire harness storage function is proposed, including an adapter body 1 and a housing 2, and further comprising:
[0037] The wire harness spreading assembly 3 is installed on the housing 2. The wire harness spreading assembly 3 includes a card plate 31. The outer wall of the card plate 31 has multiple card slots 33. Multiple buckles 37 are slidably connected to the card plate 31. Inside the card plate 31 and on both sides of the buckles 37, partitions 35 are symmetrically slidably connected. A first shaft 39 is rotatably connected to the card plate 31. Both ends of the first shaft 39 are fixedly connected to side plates 310. The side of the side plate 310 near the adapter body 1 abuts against the outer wall of the partition 35.
[0038] The wire harness limiting component 4 is disposed on the housing 2 and is used to limit the wire harness wound on the adapter body 1;
[0039] The connector flipping assembly 5 is mounted on the housing 2 and is used to pull out and flip the wire harness connector when the wire harness is wound.
[0040] In practical application, the user winds the wire harness to be stored around the adapter body 1 inside the housing 2. After the wire harness is laid out on the side plate 310, the inclined surface on the side plate 310 guides the wound wire harness, causing the wire harness to slide to the lowest point on the inclined surface of the side plate 310. When the side plate 310 slides to the lowest point, the corresponding slot 33 will block the wire harness, thereby fixing the wire harness inside the corresponding slot 33, thus realizing the arrangement and positioning of the first wound wire harness.
[0041] When the wire harness is positioned inside the first slot 33, the buckle 37 inside the slot 33 is squeezed and slides into the slot 31. After the buckle 37 slides, the two partitions 35 corresponding to it slide into the slot 31 together, so that the side plate 310 is no longer blocked by the partition 35 corresponding to the first slot 33. At this time, because the slide 34 and the partitions 35 are distributed in a stepped manner, the side plate 310, which is not blocked by the first partition 35, will flip and overlap on the second partition 35. When the user winds the second loop of the wire harness, the wire harness will fall into the slot 33 in the second position, and so on, so that the wire harness can be evenly spread when it is wound on the outer shell 2.
[0042] like Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, a first torsion spring 32 is fixedly connected between the card plate 31 and the outer shell 2, the partition plate 35 is slidably engaged with the sliding groove 34 opened inside the card plate 31, a first spring 36 is fixedly connected between the partition plate 35 and the card plate 31, a second spring 38 is fixedly connected between the buckle plate 37 and the card plate 31, and a second torsion spring 311 is fixedly connected between the side plate 310 and the card plate 31.
[0043] In practical applications, when a user needs to connect the adapter to power, the card plate 31 can be flipped around the outer shell 2 to expose the interface. The first torsion spring 32 is twisted to generate torque, and then the user can plug it in for use. When the adapter body 1 is finished using and needs to be stored, the user unplugs the external wiring. The first torsion spring 32 returns to its original position and flips the card plate 31 to fit against the adapter body 1, thereby protecting the wiring port of the adapter body 1.
[0044] During the winding process, when the buckle plate 37 slides downward, the corresponding second spring 38 will be compressed and elastically contracted. After the buckle plate 37 slides, the partition 35 is no longer resisted by its outer wall. The elastic contraction of the first spring 36 drives the partition 35 to slide into the clamping plate 31. After the partition 35 slides into the clamping plate 31 at a certain point, the second torsion spring 311 will release torque to make the side plate 310 rotate on the clamping plate 31, so that the side plate 310 overlaps the partition 35 at the next point.
[0045] like Figure 5 and Figure 7 As shown, in another preferred embodiment of the present invention, the slide 34, the partition 35 and the buckle 37 are all distributed in a stepped manner inside the card plate 31, the side of the side plate 310 away from the partition 35 is an inclined surface, and the second torsion spring 311 has a torque that causes the side plate 310 to twist toward the adapter body 1.
[0046] In practical application, each loop of the wire harness will slide on the inclined surface of the side plate 310. The sliding groove 34, the partition plate 35 and the buckle plate 37 are all distributed in a stepped manner inside the clamping plate 31, so that each loop of the wire harness can be confined in multiple clamping slots 33 one by one, thereby achieving uniform storage of the wire harness on the adapter body 1.
[0047] The even spreading of the wire harness by the slots 33 on the card plate 31 makes the wire harness more orderly when winding and storing, avoiding the problem of wear caused by the wire harness being squeezed against each other. The card plate 31 can also seal the interface when the adapter body 1 is not in use, preventing external pollution and oxidation of the interface of the adapter body 1, and improving the service life of the equipment.
[0048] like Figure 8 As shown, in another preferred embodiment of the present invention, the wire harness limiting assembly 4 includes a second shaft 41 fixedly connected to the housing 2, a gear 42 fixedly connected to the middle section of the second shaft 41, a cover plate 43 rotatably connected to the second shaft 41, a rubber roller 45 movably connected to the side of the cover plate 43 near the adapter body 1, a gear shaft 44 rotatably connected inside the cover plate 43, the gear shaft 44 meshing with a bevel tooth 46 fixedly connected to the rubber roller 45, a T-shaped plate 47 fixedly connected to the end of the rubber roller 45 away from the second shaft 41, a sloping groove 48 adapted to the T-shaped plate 47 is provided on the housing 2, the inner wall of the sloping groove 48 is sloping, a first magnetic plate 49 with opposite magnetic properties is provided on the cover plate 43 and the housing 2, and a fifth spring 410 is fixedly connected between the rubber roller 45 and the cover plate 43.
[0049] In practical application, the user flips the cover plate 43 around the second shaft 41 to open it. After the wire harness is wound around the adapter body 1, the user flips the cover plate 43 to close it.
[0050] During the flipping and closing process of the cover plate 43, the gear shaft 44 inside the cover plate 43 meshes with the gear 42 and rotates. When the gear shaft 44 rotates, it drives the rubber roller 45 to rotate together through meshing with the bevel gear 46. After the rubber roller 45 rotates, the fifth spring 410 twists and generates torque. When the T-shaped plate 47 on the rubber roller 45 slides into the inclined groove 48, the rubber roller 45 has already squeezed the wire harness wound on the adapter body 1. The inclined surface of the inclined groove 48 will squeeze the T-shaped plate 47. The mold plate 47 drives the rubber roller 45 to slide at the bottom of the cover plate 43. At this time, the bevel tooth 46 and the tooth shaft 44 on the rubber roller 45 no longer mesh, and the torque of the fifth spring 410 in the early stage is released. The rotational potential energy of the rubber roller 45 will straighten the wire harness wound on the adapter body 1 through friction. This allows the wire harness to be more tightly stored on the adapter body 1 after being limited by the cover plate 43, avoiding the problem that the wire harness is easily pulled and damaged on the adapter body 1 due to loose winding.
[0051] like Figure 1 , Figure 9 and Figure 10 As shown, in another preferred embodiment of the present invention, the connector flipping assembly 5 includes a shaped groove 58 formed on the outer shell 2. A positioning frame 51 is movably connected inside the shaped groove 58. A toothed disc 52 is fixedly connected to the outer wall of the positioning frame 51. The toothed disc 52 of the positioning frame 51 is located inside the outer shell 2. An arc-shaped plate 53 is slidably connected to the outer shell 2. A third spring 54 is fixedly connected between the arc-shaped plate 53 and the outer shell 2. A push plate 55 is slidably connected inside the outer shell 2. A fourth spring 56 is fixedly connected between the push plate 55 and the outer shell 2. The side of the push plate 55 near the positioning frame 51 is inclined and a toothed plate 57 is fixedly connected to the wall. A second magnetic plate 59 with opposite magnetic poles is fixedly connected to the positioning frame 51 and the adapter body 1.
[0052] In practical application, after the user wraps the wire harness around the adapter body 1 once, the arc plate 53 will be squeezed by the wire harness and slide towards the side closer to the adapter body 1. The third spring 54 will be stretched and extended. After the arc plate 53 slides, it will squeeze the inclined surface of the push plate 55, causing the push plate 55 to slide inside the outer shell 2. After the push plate 55 slides, the inclined surface away from the arc plate 53 will squeeze the positioning frame 51, causing the positioning frame 51 to slide towards the circular end of the irregular groove 58 inside the irregular groove 58. As the positioning frame 51 slides, the wire harness connector inserted in the middle section of the positioning frame 51 will be pulled out from the adapter body 1 together. When the toothed plate 57 on the push plate 55 meshes with the toothed disc 52, the sliding of the push plate 55 will drive the positioning frame 51 to rotate inside the circular end of the irregular groove 58, thereby flipping the wire harness connector from a perpendicular state to a parallel state.
[0053] When the wire harness is wound, the connector flipping component 5 can effectively protect the wire harness connector from damage due to excessive bending by pulling out and flipping the wire harness connector. At the same time, by rotating the wire harness connector, the area required for the wire harness to be wound on the adapter body 1 can be effectively reduced, making the wire harness more neatly stored on the adapter body 1.
[0054] like Figure 8 As shown, in another preferred embodiment of the present invention, the gear shaft 44 is provided with a threaded groove, the gear shaft 44 meshes with the bevel gear 46 through the threaded groove, the gear 42 meshes with the gear shaft 44, the surface of the rubber roller 45 is provided with a rubber strip, and the distance between the wall of the rubber roller 45 and the adapter body 1 is equal to the diameter of the wire harness.
[0055] like Figure 9 and Figure 10 As shown, in another preferred embodiment of the present invention, the middle section of the positioning frame 51 is a wire harness connector limiting hole, the side of the push plate 55 near the arc plate 53 is an inclined surface, the middle section of the irregular groove 58 to the end near the adapter body 1 is a straight groove, the end of the irregular groove 58 away from the adapter body 1 is round, and the toothed disc 52 meshes with the toothed plate 57.
[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
