Description

Technical Field

[0001] The present invention relates to the technical field of power adapters, and in particular to a power adapter with a wire-reeling function. Background Art

[0002] With the widespread use of electronic devices, power adapters, as the key power supply device connecting the power source to the device, have become an indispensable accessory for various electronic products. Existing power adapters typically consist of a housing, a built-in power module, and AC and DC power cables for connecting the external power source to the device. In actual use, users need to pull the power cable from the adapter and plug it into an outlet or device according to the usage scenario, and then store it after use.

[0003] However, traditional power adapters often use exposed or simply coiled cable storage, lacking effective cable-retraction mechanisms. This leads to problems such as tangling, tangling, and damage during use and storage. Furthermore, the cables are easily contaminated with dust and foreign matter during use, hindering their storage and usability. Furthermore, the lack of fixed and retaining structures can cause the cables to slip unexpectedly during plugging and unplugging due to uneven force, compromising operational stability.

[0004] Therefore, it is necessary to design a power adapter with a wire-retracting function to solve the above technical problems. Summary of the Invention

[0033] like Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 As shown, it also includes a slide bar 21, a second push rod 18, a connection limit block 1801 and a second spring 20. A slide bar 21 is symmetrically slidably provided on the right side of the power supply 5. The upper and lower sides of the slide bar 21 are slidably matched with the winding seat 8. The side of the slide bar 21 close to each other abuts against the AC power cord 6. The left and right ends of the slide bar 21 are slidably connected to the second push rod 18. The second push rod 18 is fixedly connected to the shell 1. The slide bar 21 and the second push rod 18 are horizontally and vertically arranged. The slide bar 21 can move back and forth along the length direction of the second push rod 18. The end of the second push rod 18 away from the shell 1 passes through the slide bar 21 and is convexly provided with a connection limit block 1801. The second spring 20 is sleeved and installed on the second push rod 18. One end of the second spring 20 is connected to the connection limit block 1801, and the other end is connected to the slide bar 21.

[0034] like Figure 3 、 Figure 5 、 Figure 6 and Figure 7As shown, it also includes a rack 19, a rubber ring 22 and a gear ring 23. A rack 19 is fixed on the right side of the slide rod 21, and the two racks 19 are arranged symmetrically up and down. The rubber ring 22 is rotatably connected to the notch on the right side of the shell 1, and a gear ring 23 is fixed on the outer periphery of the left side of the rubber ring 22. The gear ring 23 is engaged with the racks 19 on the upper and lower sides.

[0035] like Figure 3 、 Figure 4 and Figure 6 As shown, it also includes a ratchet 9, a slider 24, a pawl 25 and a third spring 26. The ratchet 9 is fixed on the periphery of the clamping column at the top of the winding seat 8. A limiting groove is opened on the right side of the top of the shell 1. The slider 24 is slidably connected in the limiting groove. The pawl 25 is fixed at the bottom of the slider 24. The pawl 25 is stuck in the tooth groove on the ratchet 9. A third spring 26 is provided between the slider 24 and the shell 1.

[0036] like Figure 8 As shown, it also includes a heat dissipation pad 27, a refrigerator 28 and a circulation pipe 29. A heat dissipation pad 27 is provided on the top of the power supply 5, and a refrigerator 28 is installed on the left side of the top of the partition 7. A circulation pipe 29 is connected to the left side of the refrigerator 28, and the circulation pipe 29 is located on the upper part of the heat dissipation pad 27.

[0037] The operator can apply the corresponding technical solutions in the present device to the cable retraction and release operation of the power adapter according to specific circumstances. When the present device is needed to assist in the storage or use of the AC power cord 6, first, the AC power cord 6 extending from the notch on the right side of the shell 1 is held and pulled out. At this time, the reel seat 8 rotates, the spiral spring 10 is compressed, and the reel seat 8 drives the ratchet 9 to squeeze the pawl 25 to move back and forth under the action of the third spring 26. The pawl 25 can prevent the ratchet 9 from reversing. After being pulled out to a suitable distance, the AC power cord 6 can be released, thereby conveniently pulling the AC power cord 6 out of the shell 1 for use; Initially, the second spring 20 is in a stretched state. When the AC power cord 6 is pulled outward, the slide bars 21 on both sides approach each other under the resetting action of the second spring 20, and form a clamping area between the second push rod 18, applying a certain elastic clamping force to the AC power cord 6, so that it maintains a stable path during movement, avoiding deviation and uneven winding or jamming; then the DC power cord 2 is pulled out from the holder 4 of the shell 1. During the pulling process, the roller 3 slides in contact with the DC power cord 2, so that the excess DC power cord 2 is neatly stored. If the distance is far, it can be directly wound out from between the rollers 3 and stretched to the vicinity of the device for connection.

[0038] When the use is completed and the cable is ready for storage, the operator only needs to push the slider 24 to the right, the third spring 26 is compressed, the pawl 25 disengages the ratchet 9, and the spiral spring 10 releases energy to push the reel seat 8 to rotate, automatically retracting the AC power cord 6 into the housing 1; during this process, the rack 19 on the slide rod 21 drives the gear ring 23 on the rear side of the rubber ring 22 to rotate with the movement, and the rubber ring 22 rotates and contacts the surface of the cable, realizing a cleaning function under the action of friction, which helps to remove dust and impurities and improves safety in use.

[0039] When the AC power cord 6 is retracted to the end, the connector of the AC power cord 6 will squeeze the buffer pad 14 under the restoring force of the spiral spring 10, the first spring 15 will be stretched, and the buffer pad 14 will drive the first push rod 16 to slide to the left, and the slide groove 17 on the first push rod 16 will squeeze the limit rod 12 to slide upward, so that the limit rod 12 drives the clamping ring 11 to slide upward synchronously, and further, the clamping ring 11 will be stuck in the upper clamping groove of the clamping column, so that the clamping ring 11 will limit the clamping column and the winding seat 8 to prevent the winding seat 8 from rotating at will. When the AC power cord 6 needs to be pulled out for use, it is only necessary to press the clamping ring 11 so that the clamping ring 11 slides out of the upper clamping groove of the clamping column, thereby releasing the restriction of the clamping column and the winding seat 8, so that the AC power cord 6 can be pulled out conveniently.

[0040] In addition, during long-term power-on use, the heat generated by the power supply 5 will diffuse to the heat dissipation holes through the heat dissipation pad 27. If the heat continues to generate, the refrigerator 28 can be turned on for cooling. The cold air is transferred to the heat dissipation pad 27 through the circulation pipe 29 to maintain the internal temperature of the shell 1 within a reasonable range, thereby extending the service life of the electronic components and ensuring the safe operation of the equipment.

[0041] In summary, the device, through the coordinated cooperation of multiple functional modules, enables convenient cord retraction and deployment, flexible locking, path guidance, cleaning and maintenance, and excellent temperature control. This not only improves overall convenience and safety, but also enhances the product's practicality and durability, and has promising market application prospects.
